Members in this family, classified into six isotypes that are tissue- and organ-specific, hydrolyze phosphatidylinositol 4,5-bisphosphate just before the phosphate group to yield diacylglycerol and inositol 1,4,5-trisphosphate. This protein localizes to the acrosome in spermatozoa and elicits Ca(2+) oscillations and egg activation during fertilization that leads to early embryonic development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]. * **UniProt Summary**: The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes. In vitro, hydrolyzes PtdIns(4,5)P2 in a Ca(2+)- dependent manner. 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 is transferred from the sperm into the egg cytoplasm following gamete membrane fusion. May exert an inhibitory effect on phospholipase-C-coupled processes that depend on calcium ions and protein kinase C, including CFTR trafficking and function. {ECO:0000250|UniProtKB:Q8K4D7, ECO:0000269|PubMed:12416999, ECO:0000269|PubMed:14697805, ECO:0000269|PubMed:15579586, ECO:0000269|PubMed:26721930, ECO:0000305}. |C2| |PI-PLC-X| |PI-PLC-Y| |efhand like| |positive regulation of cytosolic calcium ion concentration involved in egg activation| |egg activation| |pronucleus| |sperm head| |inositol trisphosphate biosynthetic process| |phosphatidylinositol-5-phosphate binding| |inositol trisphosphate metabolic process| |phosphatidylinositol phospholipase C activity| |inositol phosphate biosynthetic process| |phosphatidylinositol-3-phosphate binding| |inositol phosphate metabolic process| |polyol biosynthetic process| |phosphatidylinositol-4,5-bisphosphate binding| |polyol metabolic process| |alcohol biosynthetic process| |single fertilization| |fertilization| |organic hydroxy compound biosynthetic process| |calcium ion transport| |positive regulation of cytosolic calcium ion concentration| |divalent metal ion transport| |lipid catabolic process| |divalent inorganic cation transport| |alcohol metabolic process| |regulation of cytosolic calcium ion concentration| |cellular calcium ion homeostasis| |calcium ion homeostasis| |organic hydroxy compound metabolic process| |cellular divalent inorganic cation homeostasis| |divalent inorganic cation homeostasis| |organophosphate biosynthetic process| |cellular metal ion homeostasis| |small molecule biosynthetic process| |metal ion homeostasis| |cellular cation homeostasis| |metal ion transport| |cellular ion homeostasis| |perinuclear region of cytoplasm| |cation homeostasis| |inorganic ion homeostasis| |calcium ion binding| |cellular chemical homeostasis| |ion homeostasis| |cation transport| |sexual reproduction| |nucleolus| |organophosphate metabolic process| |cellular homeostasis| |multi-organism reproductive process| |cell activation| |chemical homeostasis| |lipid metabolic process| |ion transport| |reproductive process| |reproduction| |homeostatic process| |intracellular signal transduction| |small molecule metabolic process| |organic substance catabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp535|Trimetrexate 0.03μM R08 exp535]]|-1.82| |[[:results:exp485|GSK626616 14μM R08 exp485]]|-1.7| |[[:results:exp150|SGC0649 7μM R03 exp150]]|1.74| |[[:results:exp40|2-Methoxyestradiol 0.2μM R01 exp40]]|1.8| |[[:results:exp60|Vinblastine 0.002μM R01 exp60]]|2.17| No correlation found to any other genes in chemogenomics.
