Immunological demonstration of epsilon PKC. Murine tissue distribution, ontogeny, cellular localization and translocation.
An antiserum raised against an epsilon PKC-specific peptide recognizes epsilon PKC with an apparent molecular weight of 97 kDa in cytosol of mouse brain. No cross-reaction with alpha, beta, gamma PKC or the delta PKC-like p76-kinase is observed. Epsilon PKC is mainly present in brain. Just traces of this PKC isoenzyme can be detected in some other murine tissues. Ontogenetic studies indicate that the amount of epsilon PKC in murine brain increases constantly and reaches a maximal level at day 7 after birth. Upon TPA activation epsilon PKC is translocated from the cytosol to the particulate fraction in a brain homogenate.
