==STRUCTURE OF THE PLECKSTRIN HOMOLOGY DOMAIN FROM PHOSPHOLIPASE C DELTA IN COMPLEX WITH INOSITOL TRISPHOSPHATE==
-
The X-ray crystal structure of the high affinity complex between the, pleckstrin homology (PH) domain from rat phospholipase C-delta 1, (PLC-delta 1) and inositol-(1,4,5)-trisphosphate (Ins(1,4,5)P3) has been, refined to 1.9 A resolution. The domain fold is similar to others of known, structure. Ins(1,4,5)P3 binds on the positively charged face of the, electrostatically polarized domain, interacting predominantly with the, beta 1/beta 2 and beta 3/beta 4 loops. The 4- and 5-phosphate groups of, Ins(1,4,5)P3 interact much more extensively than the 1-phosphate. Two, amino acids in the PLC-delta 1 PH domain that contact Ins(1,4,5)P3 have, counterparts in the Bruton's tyrosine kinase (Btk) PH domain, where, mutational changes cause inherited agammaglobulinemia, suggesting a, mechanism for loss of function in Btk mutants. Using electrostatics and, varying levels of head-group specificity, PH domains may localize and, orient signaling proteins, providing a general membrane targeting and, regulatory function.

== Function ==
 +
[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.
