Title

THE ROLE OF ACROSIN IN REPRODUCTION

Pages

  38-43

Abstract

ACROSIN, an end protease with trypsin-like substrate specificity, is localized in the acrosomal matrix as an enzymatic ally inactive zymogen, proACROSIN that is then converted into the active form as a consequence of the ACROSOME REACTION.The physiological role of ACROSIN in fertilization has long been believed to be the limited proteolysis of the zona pellucida. Using homologous recombination, we have previously successfully produced male mice carrying a disruptive mutation in the ACROSIN gene and found that the mouse sperm lacking ACROSIN protease activity still penetrate zona pellucida and normally fertilize the egg .These Results provide evidence, that ACROSIN is not essential for sperm penetration of the zona pellucida. However, mouse sperm lacking ACROSIN showed a delay in penetration of the zona pellucida solely at the early stage after insemination .To elucidate the role of ACROSIN in fertilization; we have examined the involvement of ACROSIN in fertilization of zona pellucida after hardening and agining. We used DMSO for the hardening of zona pellucida. We observed that sperm lacking ACROSIN showed a reduced fertilization of eggs after zona pellucida hardening and aging. These data suggest the role of ACROSIN in COMBINED INFERTILITY, which male and female factors are involved
