[0001] The present disclosure relates to a device, method and computer program for determining a target protein by considering the degree of surface exposure obtained from a three-dimensional structure of a fusion protein, characterized in that the fusion protein is simulated to calculate an average degree of surface exposure, and the degree of activation of the fusion protein, cancer causative action information, etc. are determined by using the degree of surface exposure.
[0002] Gene fusion refers to the process of combining genes from two or more different organisms to create a single new gene. Gene fusion is a technique commonly used in genetic manipulation and genetic engineering research. It is utilized in fields such as creating genes with new characteristics or genes that perform specific functions.
[0003] Gene fusions can be utilized as a novel approach to predicting cancer causation. These methods can provide information on the occurrence and type of gene fusion.

[0060] According to one embodiment of the present disclosure, the memory (140) can store a program for processing and controlling the processor (110) and / or the characteristic determination unit (200), and can also store data input to or output from the fusion protein analysis device (100). According to one embodiment of the present disclosure, the memory (140) can store information regarding a user account, or information regarding a fusion protein. The memory (140) can store information regarding a normal sample, and information regarding a correlation coefficient between a fusion protein and a disease.

[0063] Figure 3 is a drawing showing the detailed structure of the characteristic determination unit (120).
[0064] The characteristic determination unit (120) may be in the form of a set of commands implementing a function or a program generated by compiling these commands. The characteristic determination unit (120) may include a sequence conversion unit (121), a three-dimensional structure generation unit (122), a surface degree calculation unit (123), an activation degree calculation unit (124), and a data output unit (125).

[0065] The characteristic determination unit (120) can determine the correlation coefficient between the information on the user's fusion protein obtained by analyzing the sample cells and the user's disease.
[0066] The sequence conversion unit (121) can extract RNA from a sample cell of a user infected with a disease and analyze the RNA sequence through NGS (Next generation sequencing). For example, the sample cell of a user infected with a disease may be tissue, blood, saliva, sweat, etc. The sequence conversion unit (121) can convert the analyzed data into protein sequence data. The sequence conversion unit (121) can compare data on the user's RNA with data on the RNA of normal cells to select information on a fusion gene generated in the user's genome. The sequence conversion unit (121) can generate protein sequence data of the fusion gene. The protein sequence data may include data on a fusion protein in a region where the fusion gene is detected. The data generated by the sequence conversion unit (121) may include one or more fusion genes included in the user's RNA and data on a fusion protein included in each fusion gene. The protein sequence data generated by the sequence conversion unit (121) may be as illustrated in FIG. 5A. It may include information on the fusion gene, structure variation of the fusion gene, prediction confidence, reading frame, fused protein domains, cancer-related fusion, and target of proliferation. The sequence conversion unit (121) may generate an image of the fusion gene through NGS analysis, as illustrated in FIG. 5b. The fused protein domains may be obtained by searching a domain database. The domain database may be Pfam, LiterPro, etc. The domain information of the fusion protein is as illustrated in FIG. 5c.
[0067] The three-dimensional structure generation unit (122) can generate data on a three-dimensional protein structure by inputting protein sequence data into the structure generation module. The input protein sequence data may be for a fusion protein. The structure generation module may be Alphafold2, but is not limited thereto and various structure generation modules may be used. Through the three-dimensional structure generation unit (122), the three-dimensional structure of the fusion protein can be output as shown in Fig. 6a.
[0068] As illustrated in FIG. 6B, one-dimensional sequence text data (A1) and three-dimensional structure text data (A2) can be converted into text format and stored through embodiments of the present disclosure. The one-dimensional sequence text data (A1) is data obtained by performing NGS (Next generation sequencing) on a user's RNA sequence, and may be in FASTA format. The three-dimensional structure data (A2) is data output from a structure generation module converted into text format, and may be in PDB format.
[0069] The surface output unit (123) can input data on the three-dimensional protein structure of the fusion protein into the simulation module to generate data that virtually shapes the fusion protein. The simulation module can simulate the dynamic movement of the fusion protein by considering the interaction between each atom in the fusion protein structure and generate simulated data. The surface output unit (123) can use the virtual model of the fusion protein generated according to the simulation results to produce surface-related information, such as the degree of surface exposure in the fusion protein. Through the simulation process, the surface output unit (123) can select the initial positions of the atoms forming the fusion protein, assign an initial movement velocity to each atom, and calculate the momentum according to the mass and assigned velocity of each atom. The surface output unit (123) can calculate the force applied to each atom according to the force existing between the atoms, and measure the movement and positional change of each atom according to this force. Through the above process, a virtual model of the fusion protein can be generated. The surface output unit (123) can determine the movement of the fusion protein through a virtual model and obtain the surface exposure area of the fusion protein. The surface output unit (123) can calculate the surface exposure degree, surface shape, etc. for the surface exposure area. The surface output unit (123) can output surface-related information including the surface exposure degree, surface shape, etc. at one or more time points. The surface output unit (123) can determine an average value of one or more surface exposure degrees derived from the fusion protein as a representative surface exposure degree using a simulation module. The surface output unit (123) can determine an average value of one or more surface shapes derived from the fusion protein as a representative surface shape.
[0070] Here, surface exposure refers to the sum of the surface areas exposed to each molecule that makes up the protein. Surface exposure can be calculated as the sum of the surface areas exposed to each molecule, taking into account factors such as the radius from the center of each molecule and the distance between molecules. The surface area exposed to the outside of a molecule can be calculated using the formula for calculating the surface area of a sphere.
[0071] The activation degree calculation unit (124) can obtain functional classification information of the fusion protein using identification information about the fusion protein. The functional classification information can include a first fusion gene, a second fusion gene, structure variation, prediction confidence, a reading frame, fused protein domains, cancer-related fusion, a target of proliferation, etc., as illustrated in FIG. 5A. The first fusion gene and the second fusion gene refer to two genes that make up the fusion protein. The activation degree calculation unit (124) can determine functional classification information of the fusion protein using a database such as a gene ontology.
[0072] Functional classification information for a protein may include information about whether the fusion protein is involved in a biological process or pathway, such as the fusion protein's name or ID value. In particular, this may include the extent to which the fusion protein has an oncogenic effect.
[0073] The activation degree calculation unit (124) can find terms related to the fusion protein and obtain functional classification information of the fusion protein based on the terms. The functional classification information of the fusion protein can include information on the fusion gene, structural variation, prediction confidence, reading frame, fused protein domains, cancer-related fusion, target of proliferation, etc.
[0074] The data output unit (125) can calculate the activation degree of the fusion protein based on the surface-related information and functional classification information of the fusion protein. Functional classification information that changes according to the surface exposure degree of the fusion protein can be selected, and the activation value of the fusion protein can be calculated based on the functional classification information that has a proportional or inverse relationship to the surface exposure degree. For example, if the cancer-related fusion increases as the surface exposure degree increases, the activation value of the fusion protein can be calculated by combining the values of the surface exposure degree of the fusion protein and the cancer-related fusion degree. Even if the surface exposure degree increases, if the cancer-related fusion degree is a constant value, the activation value of the fusion protein can be calculated by considering the surface exposure degree.
[0075] The data output unit (125) can calculate the degree of cancer-causing activity of the fusion protein based on surface-related information of the fusion protein. For example, if the cancer-related fusion increases as the degree of surface exposure increases, the fusion protein can be classified as having a degree of cancer-causing activity calculated according to the degree of surface exposure. The value of cancer-related fusion according to the degree of surface exposure can be calculated based on the correlation coefficient between the value of the degree of surface exposure and the value of cancer-related fusion. If the degree of surface exposure exceeds a preset reference value, it is determined that the fusion protein acts as a cancer-causing activity, and the degree of cancer-causing activity can be calculated as 1 (TRUE). The degree of cancer-causing activity can be set as a value proportional to the degree of surface exposure.
[0076] The above processes can be output by the surface analysis module. The data output unit (125) can calculate the correlation coefficient between the surface-related information of the fusion protein and the functional classification information of the fusion protein, and can perform machine learning of the surface analysis module using the surface-related information of the fusion protein and the functional classification information of the fusion protein, the correlation coefficient between the surface-related information and the functional classification information, etc. as a training data set.
[0077] The surface analysis module can be trained using a training data set containing fusion protein identification information (name, ID, etc.), surface-related information, and cancer causal action information. The surface analysis module can be trained using machine learning or deep learning methods. The surface analysis module can be trained using methods such as reinforcement learning or unsupervised learning. The surface analysis module can be trained by inferring correlations between cancer types and fusion proteins.
[0078] For example, if the genomic data of a first user is acquired and the occurrence of a first fusion protein is confirmed in the genomic data, surface-related information of the first fusion protein can be calculated. Based on the surface-related information of the first fusion protein, information such as whether the first user is at risk of developing a cancer or the likelihood of developing a disease such as cancer, the degree of cancer-causing effect, etc. can be calculated and output. At this time, the presence or degree of cancer-causing effect can be calculated only for a specific cancer, that is, for each cancer type.
[0079] According to embodiments of the present disclosure, for gene fusion, surface-related information such as the degree of surface exposure of the fusion protein is obtained using the three-dimensional structure of the fusion protein and a virtual model of the fusion protein, and based on the surface-related information of the fusion protein, whether the fusion protein has an oncogenic effect, the degree of the oncogenic effect, etc. can be calculated. At this time, a surface analysis module trained by a method such as machine learning or deep learning can be used. The surface analysis module can be implemented to take the degree of identification of the fusion protein and the surface-related information as input and output the degree of activation of the fusion protein and information on the oncogenic effect. Through this, it is also possible to determine whether the fusion protein can be used as a target gene based on the oncogenic effect information of the fusion protein.
[0080] According to embodiments of the present disclosure, it is possible to determine whether a fusion protein can be used as a target gene for a specific cancer by using the degree of activation of the fusion protein and information on its cancer-causing action.
[0081] Here, the cancer-causing effect information may be a value determined by cancer type. For example, by analyzing the surface exposure of a fusion protein, cancer-causing effect information for breast cancer and cancer-causing effect information for lung cancer can be derived, respectively. The cancer-causing effect information may include whether the protein contributes to cancer development and a probability value for the likelihood of cancer development. The value for whether the protein contributes to cancer development may be set to either "Yes" or "No," and the probability value for the likelihood of cancer development may be a percentage.

[0086] As illustrated in FIG. 6B, one-dimensional sequence text data (A1) and three-dimensional structure text data (A2) can be converted into text format and stored through embodiments of the present disclosure. The one-dimensional sequence text data (A1) is data obtained by performing NGS (Next generation sequencing) on a user's RNA sequence, and may be in FASTA format.

[0087] In S130, the fusion protein analysis device (100) can input data on the three-dimensional protein structure of the fusion protein into the simulation module to virtually model the fusion protein. The simulation module can simulate the dynamic movement of the fusion protein by considering the interaction between each atom in the fusion protein structure and generate simulated data. Through the simulation process, the fusion protein analysis device (100) can select the initial positions of the atoms forming the fusion protein, assign an initial movement velocity to each atom, and calculate the momentum according to the mass and assigned velocity of each atom. The fusion protein analysis device (100) can calculate the force applied to each atom according to the force existing between the atoms, and measure the movement and positional change of each atom according to this force. Through the above process, a virtual model of the fusion protein can be generated. Through the virtual model, the movement of the fusion protein can be known, and the surface exposure area of the fusion protein can be acquired.

The surface exposure degree, surface shape, etc. can be derived for the surface exposure area. The fusion protein analysis device (100) can derive the surface exposure degree, surface shape, etc. based on the virtual model.
[0089] The fusion protein analysis device (100) can output surface-related information including surface exposure degree, surface shape, etc. at one or more time points. The fusion protein analysis device (100) can determine an average value of one or more surface exposure degrees derived from the fusion protein as a representative surface exposure degree. The fusion protein analysis device (100) can determine an average value of one or more surface shapes derived from the fusion protein as a representative surface shape.
[0090] In S150, the fusion protein analysis device (100) can calculate the degree of activation of the fusion protein based on surface-related information of the fusion protein.
[0091] The fusion protein analysis device (100) can calculate the degree of cancer-causing action of a fusion protein based on surface-related information of the fusion protein.
[0092] The above information can be output by the surface analysis module. The fusion protein analysis device (100) can calculate a correlation coefficient between the surface-related information of the fusion protein and the functional classification information of the fusion protein, and can perform machine learning of the surface analysis module using the surface-related information of the fusion protein and the functional classification information of the fusion protein, the correlation coefficient between the surface-related information and the functional classification information, etc. as a training data set.

At this time, a surface analysis module trained by a method such as machine learning or deep learning can be used. The surface analysis module can be implemented to take the degree of identification of the fusion protein and the surface-related information as input and output the degree of activation of the fusion protein and information on the oncogenic effect. Through this, it is also possible to determine whether the fusion protein can be used as a target gene based on the oncogenic effect information of the fusion protein.
