Phorbol ester-induced down-regulation of the 80-kDa myristoylated alanine-rich C-kinase substrate-related protein in Swiss 3T3 fibroblasts. Inhibition by staurosporine.

A polyclonal antiserum raised against an oligopeptide with an amino acid sequence corresponding to a sequence of the myristoylated alanine-rich C-kinase substrate (MARCKS) from mouse macrophages and rat brain recognizes the 80-kDa C-kinase substrate from Swiss 3T3 fibroblasts. Using this antiserum for quantitative determination of the 80-kDa MARCKS-related protein, we found that the phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA) induces a rapid down-regulation of this protein in the fibroblasts. In accordance with earlier reports, TPA causes phosphorylation of the 80-kDa protein which can be inhibited by staurosporine. Staurosporine also suppresses the TPA-induced down-regulation, possibly indicating that the down-regulation of the MARCKS-related protein is dependent on its phosphorylation by protein kinase C.[1]
