A Kinase Anchor Protein-12 Definition

Encoded by human AKAP12 Gene, A Kinase Anchor Protein 12 is expressed in endothelial cells, but not in platelets or peripheral blood cells. The 1,781-amino acid 191 kD cytoplasmic anchoring protein appears to mediate compartmentation of PKA and PKC in the cortical cytoskeleton. Its amphipathic alpha helix binds to the PKA RII subunit and tethers the enzyme near its substrates. Activated by lysopc, AKAP12 inhibits PKC. Polybasic regions are involved in binding PKC. (OMIM, Swiss-Prot, and NCI)
