Ca2+/calmodulin-dependent protein kinases are implicated in regulating the Ca2+ signaling involved in T cell activation and in thymocyte selection. One of the earliest events in signaling through the T cell antigen receptor is activation of the protein tyrosine kinase p56lck. Following T cell activation or signaling through the IL-2 receptor, Ca(2+)-mediated phosphorylation of p56lck occurs on serine/threonine residues. Isoforms of the multifunctional Ca2+/calmodulin-dependent protein kinases, CaM kinase-II and CaM kinase-Gr are found in human T lymphocytes. CaM kinase-II, but not CaM kinase-Gr, phosphorylates the T cell tyrosine kinase p56lck in vitro. Tryptic phosphopeptide maps indicate that CaM kinase-II phosphorylates p56lck on multiple sites in vitro. Kinase assays of p56lck modified by CaM kinase-II indicate that CaM kinase-II modification does not appreciably affect p56lck phosphotransfer activity.
