basic FUNCTION
  • serine proteinase with trypsin-like specificity
  • major proteinase present in the acrosome of mature spermatozoa
  • function both in the limited proteolysis of the zona pellucida, and in the maintenance of binding of acrosome-reacted sperm to the zona
  • having functions in the lysis of the zona pellucida, thus facilitating penetration of the sperm through the innermost glycoprotein layers of the ovum
  • MMP2 and ACR are associated with the inner acrosomal membrane (IAM) and introduces the possibility of their cooperation in enzymatic digestion of the Sperm-zona pellucida (ZP) during penetration
  • role of acrosin in acrosome exocytosis and activation of other acrosome components
  • trypsin-like serine protease in the sperm acrosome
  • CELLULAR PROCESS

    ANIMAL & CELL MODELS
  • KO acrosin-deficient mice exhibit normal fecundity except for delayed fertilization
  • litter size from acrosin-disrupted males was decreased compared to heterozygous mutant rats
