Abstract excerpt

Ca(2+)/calmodulin-dependent protein kinase phosphatase (CaMKP) is a member of the serine/threonine protein phosphatases and shares 29% sequence identity with protein phosphatase 2Calpha (PP2Calpha) in its catalytic domain. To investigate the functional domains of CaMKP, mutational analysis was carried out using various recombinant CaMKPs expressed in Escherichia coli. Analysis of N-terminal deletion mutants...
