'''PROTEIN KINASE C DELTA CYS2 DOMAIN COMPLEXED WITH PHORBOL-13-ACETATE'''
===PROTEIN KINASE C DELTA CYS2 DOMAIN COMPLEXED WITH PHORBOL-13-ACETATE===




==Overview==
<!--
Protein kinase Cs (PKCs) are a ubiquitous family of regulatory enzymes that associate with membranes and are activated by diacylglycerol or tumor-promoting agonists such as phorbol esters. The structure of the second activator-binding domain of PKC delta has been determined in complex with phorbol 13-acetate, which binds in a groove between two pulled-apart beta strands at the tip of the domain. The C3, C4, and C20 phorbol oxygens form hydrogen bonds with main-chain groups whose orientation is controlled by a set of highly conserved residues. Phorbol binding caps the groove and forms a contiguous hydrophobic surface covering one-third of the domain, explaining how the activator promotes insertion of PKC into membranes.
