  • basic FUNCTION
  • phosphoinositide phospholipase C activity
  • may be the molecular trigger for egg activation during fertilization
  • is a sperm-specific enzyme that initiates the Ca2+ oscillations in mammalian eggs that activate embryo development
  • potential role regulating not only egg activation but other sperm functions

    constitutional     --low loss of function
    abnormal PLCZ1 expression is involved in the inability of human sperm to initiate [Ca(2+)](i) oscillations leading to failure of egg activation and sterility
    constitutional germinal mutation      
    maternally inherited autosomal point mutation in PLCZ1 leads to male infertility
    constitutional        
    absence of PLCZ1 alone is sufficient to prevent oocyte activation irrespective of the presence of WBP2NL
