| + | Direct activation of the human phospholipase C-g isozymes (PLC-g1, -g2) by tyrosine phosphorylation is fundamental to the control of diverse biological processes, including chemotaxis, platelet aggregation, and adaptive immunity. In turn, aberrant activation of PLC-g1 and PLC-g2 is implicated in inflammation, autoimmunity, and cancer. Although structures of isolated domains from PLC-g isozymes are available, these structures are insufficient to define how release of basal autoinhibition is coupled to phosphorylation-dependent enzyme activation. Here we describe the first high-resolution structure of a full-length PLC-g isozyme and use it to underpin a detailed model of their membrane-dependent regulation. Notably, an interlinked set of regulatory domains integrates basal autoinhibition, tyrosine kinase engagement, and additional scaffolding functions with the phosphorylation-dependent, allosteric control of phospholipase activation. The model also explains why mutant forms of the PLC-g isozymes found in several cancers have a wide spectrum of activities, and highlights how these activities are tuned during disease. | ||
