UniProtKB - Q00722 (PLCB2_HUMAN)

Protein

1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase beta-2

Gene

PLCB2

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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.1 Publication

Miscellaneous

The receptor-mediated activation of PLC-beta-2 is most effectively mediated by one G-protein alpha subunit, alpha-16.

Catalytic activityi

1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate + H2O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol.

Cofactori

Ca2+Note: Binds 1 Ca2+ ion per subunit.
