Structural views of phosphoinositide-specific phospholipase C: signalling the way ahead.
Recent structural studies of mammalian phosphoinositide-specific phospholipase C (PI-PLC) have begun to shed light on the mechanism whereby this family of effector enzymes is able to hydrolyze phospholipid substrates to yield second messengers. PI-PLC isozymes employ a variety of modules (PH domain, EF-hand domain, SH2 domain, SH3 domain and C2 domain) that are common in proteins involved in signal transduction to reversibly interact with membranes and protein components of the signalling pathways.
