The structure of the PH-domain truncated core of rat, phosphoinositide-specific phospholipase C-delta 1 has been determined at, 2.4 A resolution and compared to the structure previously determined in a, different crystal form. The stereochemical relationship between the EF, catalytic, and C2 domains is essentially identical. The Ca2+ analogue Sm3+, binds at two sites between the jaws of the C2 domain. Sm3+ binding ejects, three lysine residues which bridge the gap between the jaws and occupy the, Ca2+ site in the apoenzyme, triggering a conformational change in the, jaws. The distal sections of the C2 jaws move apart, opening the mouth by, 9 A and creating a gap large enough to bind a phospholipid headgroup.

[https://www.uniprot.org/uniprot/PLCD1_RAT PLCD1_RAT] 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. Essential for trophoblast and placental development.
