The application relates to the technical field of biological medicine, and discloses a drug composition containing nuclear autoantigen sperm protein for promoting myocardial regeneration and repair and application, which comprises an NASP gene; the nucleotide sequence of the NASP gene is shown as SEQ ID NO:1, and the amino acid sequence encoded by the NASP gene is shown as SEQ ID NO:2. The drug composition can promote the number of myocardial cells, repair the necrotic myocardium, and thus improve acute myocardial infarction at the gene level.

The present disclosure describes proteins that specifically bind to human sperm protein 17 (Sp17) with nanomolar affinity and high specificity. These proteins include recombinant human anti-Sp17 IgG, which are suitable for use as therapeutic antibodies to treat cancers that express Sp17 ectopic. Other Sp17 binding proteins, including antibody fragments, antibody conjugates, and fusion proteins, are also described.

The invention discloses an application of FXYD1 protein in sperm centromere detection. The amino acid sequence of the FXYD1 protein is as shown in SEQ ID NO. 1. By identifying an antibody of the FXYD1 protein, the expression position of the FXYD1 protein on the sperm is marked, and the number and position of centromere in the sperm are analyzed by combining immunostaining and microscope observation. The method can effectively evaluate the sperm centromere structure state, including existence, number and position form of centromere; the related expression of the sperm FXYD1 protein can also be evaluated. The human sperm quality evaluation method provided by the invention is helpful for objectively judging sperm functions, embryonic development after fertilization, physiological and pathological states related to male fertility and prognosis results of the physiological and pathological states, and has important transformation and popularization values and wide application prospects in the fields of reproductive biology and reproductive medicine.
