Protein existence	Evidence at protein level

General annotation (Comments)

Function	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. It is a crucial enzyme in transmembrane signaling.
Catalytic activity	1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H2O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol.
Cofactor	Calcium.
Subunit structure	Interacts (via SH2 domain) with CSF1R (tyrosine phosphorylated) By similarity.
Post-translational modification	Phosphorylated on tyrosine residues by CSF1R By similarity. Phosphorylated on tyrosine residues by BTK and SYK; upon ligand-induced activation of a variety of growth factor receptors and immune system receptors. Phosphorylation leads to increased phospholipase activity. Ref.7 Ref.8 Ref.9 Ref.10 Ref.11
Sequence similarities	Contains 1 C2 domain. Contains 1 PH domain. Contains 1 PI-PLC X-box domain. Contains 1 PI-PLC Y-box domain. Contains 2 SH2 domains. Contains 1 SH3 domain.
Sequence caution	The sequence AAA60112.1 differs from that shown. Reason: Frameshift at position 1242. The sequence AAQ76815.1 differs from that shown. Reason: Frameshift at position 1242. The sequence BAD92151.1 differs from that shown. Reason: Erroneous initiation. The sequence CAA32194.1 differs from that shown. Reason: Frameshift at position 1242.
