Structure of the protein kinase Cbeta phospholipid-binding C2 domain complexed with Ca2+.

Sutton, R.B.Sprang, S.R.

  • PubMed Abstract: 

    Conventional isoforms (alpha, beta and gamma) of protein kinase C (PKC) are synergistically activated by phosphatidylserine and Ca2+; both bind to C2 domains located within the PKC amino-terminal regulatory regions. C2 domains contain a bipartite or tripartite Ca2+-binding site formed by opposing loops at one end of the protein. Neither the structural basis for cooperativity between phosphatidylserine and Ca2+, nor the binding site for phosphatidylserine are known.
