We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Crystal structure of activated G alpha Q bound to its effector phospholipase C beta 3

Template:ABSTRACT PUBMED 20966218

Function

[GNAQ_MOUSE] Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. Regulates B-cell selection and survival and is required to prevent B-cell-dependent autoimmunity. Regulates chemotaxis of BM-derived neutrophils and dendritic cells (in vitro).[1] [2] [PLCB3_HUMAN] 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.

About this Structure

3ohm is a 2 chain structure with sequence from Homo sapiens and Mus musculus. Full crystallographic information is available from OCA.
