Abstract

The invention belongs to the field of biotechnology and medicine, and discloses a new human epididymis specific expression sperm binding protein HEL-89 as well as preparation and application thereof. The invention discloses an amino acid sequence of the HEL-89 protein and provides a recombination expression carrier carrying the DNA sequence for encoding the protein. The protein is located in the top area of a mature sperm. A RT-PCR result shows that the gene is highly expressed in the epididymis and testis. A band of about 20 KD is detected in the corpus epididymidis part with Western blot. The HEL-89 protein can be used as a target protein for researching and developing immunity contraceptive as well as clinical diagnosis and treatment for male sterility. A method for detecting a corresponding gene or protein based on development of the HEL-89 protein can be widely used for the research field of reproductive medicine.

Description

technical field

[0001] The invention belongs to the field of biotechnology and medicine. Specifically, the present invention relates to a new human epididymis expression protein HEL-89 and its coding gene and application Background technique

[0002] The development of human beings in this century is facing two serious problems: on the one hand, the global population is rapidly expanding and is expected to reach 9 billion in 2050; on the other hand, according to the World Health Organization survey, about 15% of couples are infertile The problem is that the incidence of infertility in developed countries has soared in the past 10 years, and it can be as high as 30% in developed countries in Europe, of which male factors account for about half. The World Health Organization predicts that with the increase of environmental pollution and sexually transmitted diseases and other pathogenic factors, infertility will become the third major disease after tumors and cardiovascular a...
