Studies on the primary sequence requirements for PKC-alpha, -beta 1 and -gamma peptide substrates

FEBS Lett. 1990 Dec 17;277(1-2):151-5. doi: 10.1016/0014-5793(90)80831-3.

Abstract

The substrate specificity of purified PKC-alpha, -beta and -gamma has been investigated. A series of synthetic peptides based upon the sequence surrounding serine-7 in glycogen synthase were generated and used to determine the basic residue requirements of these PKC isotypes. While PKC-alpha and -beta are indistinguishable in their phosphorylation of these peptides, PKC-gamma shows a distinct specificity profile for these synthetic substrates.
