PLC-beta, PH domain

InterPro entry
Short namePLC-beta_PH

Description

PLC-beta (PLCbeta) is regulated by heterotrimeric G protein-coupled receptors through their C2 domain and long C-terminal extension which forms an autoinhibitory helix. There are four isoforms: PLC-beta1-4. These isoforms mediate the production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) to propagate signals for several physiological responses

PLC-beta consists of an N-terminal PH domain, a EF hand domain, a catalytic domain split into X and Y halves, a C2 domain and a C-terminal PDZ. This entry represents the PH domain of PLC-beta. The PH domain of PLC-beta2 and PLC-beta3 plays a dual role, much like PLC-delta1, by binding to the plasma membrane, as well as the interaction site for the catalytic activator
