Abstract

The present invention provides an E.tenella TERT associated protein gene, and particularly relates to applications of the protein in telomerase activity regulation, wherein the protein has a negative regulation effect on the E.tenella telomerase activity, and develops the new research field for deep research on cell and molecular biology characteristics of coccidian and finding of new chicken coccidian preventing and treating drugs, vaccine acting target sites and the like. According to the present invention, the advantages of high efficiency and practicality are provided, a plurality of positive interaction proteins can be obtained through the yeast two-hybrid screening and verification so as to easily find the new function protein, and the method of the present invention is mature and is easy to operate compared with the comparative analysis, the proteomics, the transcriptomics, and other technologies; and the E.tenella virus transforming vector-mediated ribozyme provides the simple and easy-performing method for the research on the functions of the gene in the insect body.

Description

technical field [0001] The present invention provides a kind of Eimeria tenella TERT related protein gene, particularly relate to the effect of this protein in the regulation of telomerase activity, this protein is to E. tenella The telomerase activity has a negative regulating effect, may become a potential target for controlling coccidiosis, and belongs to the technical field of genetic engineering. Background technique [0002] Chicken coccidiosis is a parasitic disease that is distributed worldwide and seriously endangers the development of the chicken industry. Eimeria, as an intracellular parasite, parasitizes in the chicken intestine and causes chicken coccidiosis, which is mainly characterized by intestinal lesions, and seriously endangers the development of the poultry industry. At present, the control of coccidiosis mainly depends on the use of anticoccidiosis drugs and vaccines. However, due to the lack of detailed understanding of coccidiosis cells and molecula...
