| Research Abstract |
In mammalian fertilization, Ca^<2+> oscillations are indispensable for egg- activation. Sperm specific isotype of phospholopase C (PLCZ1) is a strong candidate for egg-activating sperm factor. In this study, regulation of Ca^<2+> oscillations by PLCZ1 was examined about nuclear localization ability and Ca^<2+> oscillation inducing activity. Moreover, PLCZ1 deficient mice were analyzed and it was shown that PLCZ1 has a pivotal role for spermatogenesis as well as an egg activation.
