ID:PLCG2_HUMAN DESCRIPTION: RecName: Full=1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase gamma-2; EC=3.1.4.11; AltName: Full=Phosphoinositide phospholipase C-gamma-2; AltName: Full=Phospholipase C-IV; Short=PLC-IV; AltName: Full=Phospholipase C-gamma-2; Short=PLC-gamma-2; 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 + H(2)O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol. COFACTOR: Calcium. SUBUNIT: Interacts (via SH2 domain) with CSF1R (tyrosine phosphorylated) (By similarity). INTERACTION: P19235:EPOR; NbExp=3; IntAct=EBI-617403, EBI-617321; PTM: 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. DISEASE: Defects in PLCG2 are the cause of familial cold autoinflammatory syndrome type 3 (FCAS3) [MIM:614468]. An autosomal dominant immune disorder characterized by the development of cutaneous urticaria, erythema, and pruritis in response to cold exposure. Affected individuals have variable additional immunologic defects, including antibody deficiency, decreased numbers of B cells, defective B cells, increased susceptibility to infection, and increased risk of autoimmune disorders. SIMILARITY: Contains 1 C2 domain. SIMILARITY: Contains 1 PH domain. SIMILARITY: Contains 1 PI-PLC X-box domain. SIMILARITY: Contains 1 PI-PLC Y-box domain. SIMILARITY: Contains 2 SH2 domains. SIMILARITY: Contains 1 SH3 domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
