Protein Kinase C Enzymes Harbor Intramolecular Interactions

The C2 and C1 domains of some Protein Kinase C Enzymes are tethered through electrostatic and hydrophobic interactions in the inactive form. We have delineated the interaction surfaces of the C2 and C1A domains as shown in this figure. Upon PKC interacting with the cell membrane in a calcium and phosphatdiylserine specific manner, the C2-C1A tether is unleashed leading to C1A-diacylglycerol coordination and activation of the enzyme.
