SnapShot: p38 MAPK Substrates

p38α mitogen-activated protein kinase (MAPK14) phosphorylates many downstream substrates, which allows this pathway to regulate a wide variety of cellular processes, including growth, proliferation, or differentiation. All p38α-mediated phosphorylations have been reported to occur on Ser or Thr residues, which are usually followed by a Pro residue. This SnapShot provides a compendium of known p38 substrates, their phosphorylation sites, and their functions.Table S1. p38α Substrates and Cellular FunctionsxDownload (.05 MB ) Table S1. p38α Substrates and Cellular Functions
