Modification
Phosphoralated
Modification Notes
The p38 mitogen-activated protein kinase (MAPK) pathway is an important mediator of cellular responses to environmental stress. The MAPKAP kinases (MAP kinase activated protein kinases) are a group of MAP kinase substrates that are themselves kinases. In response to activation, the MAP kinases phosphorylate downstream components on a consensus Pro-X-Ser/Thr-Pro motif. p38 phosphorylates and activates the serine/threonine kinases MAPKAP kinase-2 and MAPKAP kinase-3 (also designated 3pK). The activated MAPKAPK2 phosphorylates its nuclear targets CREB/ATF1, serum response factor, and E2A protein E47 and its cytoplasmic targets HSP25/27, LSP-1, 5-lipoxygenase, glycogen synthase, and tyrosine hydroxylase. Phosphorylation of threonine 334, which is located between the kinase domain and the C-terminal regulatory domain, may serve as a switch for MAPKAPK2 nuclear import and export. Threonine 222 which lies in the activation loop is also phosphorylated. Phosphorylated MAPKAPK2 masks the nuclear localization signal at its C terminus by binding to p38, and unmasks the nuclear export signal, carrying p38 to the cytoplasm.
