Anti-MARCKS

Myristoylated Alanine-Rich C Kinase Substrate (MARCKS) is a member of a family of calmodulin binding proteins that isa target for phosphorylation by protein kinase C (PKC) (1). MARCKS is concentrated in the synapses of neurons where it appears to function in synaptic vesicle cycling. MARCKS has been shown to bind both actin and calmodulin in vitro (2). Deletion of the MARCKS gene in mice results in embryonic brain defects and death (3). Phosphorylation of Ser152/156 modulates the binding of MARCKS to calmodulin (4).
