Human Gene PLCB2 (uc001zld.3) Description and Page Index
  Description: Homo sapiens phospholipase C, beta 2 (PLCB2), mRNA.
RefSeq Summary (NM_004573): The protein encoded by this gene is a phosphodiesterase that catalyzes the hydrolysis of phosphatidylinositol 4,5-bisphosphate to the second messengers inositol 1,4,5-trisphosphate (IP3) and diacylglycerol. The encoded protein is activated by G proteins and has been shown to be involved in the type 2 taste receptor signal transduction pathway. In addition, nuclear factor kappa B can regulate the transcription of this gene, whose protein product is also an important regulator of platelet responses. [provided by RefSeq, Jan 2017].

DESCRIPTION: RecName: Full=1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase beta-2; EC=; AltName: Full=Phosphoinositide phospholipase C-beta-2; AltName: Full=Phospholipase C-beta-2; Short=PLC-beta-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.
CATALYTIC ACTIVITY: 1-phosphatidyl-1D-myo-inositol 4,5- bisphosphate + H(2)O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol.
COFACTOR: Binds 1 calcium ion per subunit.
SUBUNIT: Interacts with RAC1.
MISCELLANEOUS: The receptor-mediated activation of PLC-beta-2 is most effectively mediated by one G-protein alpha subunit, alpha- 16.
SIMILARITY: Contains 1 C2 domain.
SIMILARITY: Contains 1 PI-PLC X-box domain.
SIMILARITY: Contains 1 PI-PLC Y-box domain.

ModBase Predicted Comparative 3D Structure on Q00722
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.
