CaMKII Substrate Peptide

This peptide is a substrate (Km = 7.5 mM) for calcium/calmodulin-dependent protein kinase II (CaMKII), which belongs to the CAMK Ser/Thr protein kinase family. The sequence derives from the residues 1-10 of the glycogen synthase containing a phosphorylation site at Ser-7 within the R-X-X-S/T consensus site and is amidated at the C-terminus end. CaMKII is a prominent kinase in the central nervous system that functions in long-term potentiation and neurotransmitter release. Phosphorylation of the substrate is calcium and calmodulin dependent.
