Facts about 1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase zeta-1.
Triggers intracellular Ca(2+) oscillations in oocytes solely during M phase and is involved in inducing oocyte activation and initiating embryonic development up to the blastocyst stage. Is therefore a strong candidate for the egg- activating soluble sperm factor that's transferred from the sperm to the egg cytoplasm after gamete membrane fusion.

Expressed specifically in testis and sperm. Weakly expressed in pancreatic-duct cells. Up-regulated in pancreatic-duct cells from patients with cystic fibrosis.
Nucleus. Cytoplasm, perinuclear region. Exhibits alternative cytoplasmic/nuclear localization during development. Translocates from the pronucleus into cytoplasm upon nuclear envelope breakdown for mitosis and localizes again to the pronucleus at interphase following meiosis and mitosis (By similarity).
