Substance Name: Myristoylated alanine-rich C kinase substrate
RN: 125267-21-2


  • A membrane and ACTIN CYTOSKELETON associated, N-terminal myristoylated protein that binds CALMODULIN and is a prominent substrate for PROTEIN KINASE C. Both phosphorylation and poly(ADP)-ribosylation inhibit its F-ACTIN crosslinking activity; phosphorylation also causes MARCKS to relocate from the membrane to cytoplasm.
