A	phosphoinositide phospholipase C M-CSA #28	Mammalian phospholipase C catalyses the hydrolysis of inositol lipid to inositol 1,4,5 trisphosphate and diacyl glycerol, both of which are important second messengers in Ca(II) signalling pathways. It possesses a Triose phosphate isomerase-like catalytic domain, indicating some homology with triosephosphate isomerase, but catalyses a different reaction by a mechanism more similar to the T1 RNAases.
