Research Abstract |
It is widely accepted that Calmodulin-kinase II (CaMKII) plays important roles in learning and memory. Although plasticity of synapse regulated by CaMKII, direct targets of CaMKII has poorly identified. To obtain cellular CaMKII substrates, we tried to apply unnatural amino acid incorporation method. Several phenylalanine residues in catalytic domain of CaMKII were made for subsequent incorporation of an unnatural amino acid pBpa. The pBpa were successfully incorporated on CaMKII in HEK293 cells. The covalent bonds were formed upon UV irradiation in cells expressing CaMKII mutants, especially residues, F16, F157, F171. This mutants are useful molecules to identify cellular substrate for CaMKII.
