+== Disease ==
+[https://www.uniprot.org/uniprot/PLCG2_HUMAN PLCG2_HUMAN] Defects in PLCG2 are the cause of familial cold autoinflammatory syndrome type 3 (FCAS3) [MIM:[https://omim.org/entry/614468 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.<ref>PMID:22236196</ref>
+== Function ==
+[https://www.uniprot.org/uniprot/PLCG2_HUMAN PLCG2_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. It is a crucial enzyme in transmembrane signaling.

+== Publication Abstract from PubMed ==
+Rho family GTPases are important cellular switches and control a number of physiological functions. Understanding the molecular basis of interaction of these GTPases with their effectors is crucial in understanding their functions in the cell. Here we present the crystal structure of the complex of Rac2 bound to the split pleckstrin homology (spPH) domain of phospholipase C-gamma(2) (PLCgamma(2)). Based on this structure, we illustrate distinct requirements for PLCgamma(2) activation by Rac and EGF and generate Rac effector mutants that specifically block activation of PLCgamma(2), but not the related PLCbeta(2) isoform. Furthermore, in addition to the complex, we report the crystal structures of free spPH and Rac2 bound to GDP and GTPgammaS. These structures illustrate a mechanism of conformational switches that accompany formation of signaling active complexes and highlight the role of effector binding as a common feature of Rac and Cdc42 interactions with a variety of effectors.
