abstractText | PKC-epsilon was isolated from a murine brain cDNA library. The clone, lambda 61PKC-epsilon, encoded a polypeptide of 737 amino acids that is homologous to other PKCs. Northern analysis showed that the 7 kb mRNA for this cDNA is widely expressed. The protein when expressed in COS-1 cells displayed phorbol ester-binding activity. However in order to detect the kinase activity of PKC-epsilon, it was necessary to employ a synthetic peptide substrate based upon the pseudosubstrate site. Subsequent analysis demonstrated that PKC-epsilon, while showing certain properties characteristic of the PKC family, has a quite distinct substrate specificity and is independent of Ca2+. |
