Incubation of B-chronic lymphocytic leukemia (B-CLL) cells with phorbol esters resulted in the phosphorylation of two major PKC substrates , MARCKS ( myristoylated, alanine-rich C kinase substrate ) and MRP ( MARCKS -related protein ), and of a third protein, with an apparent m.w. of 60,000 that was the most prominent protein kinase C substrate in these cells.
