MSK1 (human)

Overview
MSK1 an AGC kinase of the RSK family. Has two kinase domains connected by a regulatory linker region. Enzyme activity requires the presence of both kinase domains. Is phosphorylated and activated by Erk as well as p38 MAPK in response to growth factors and cellular stress. Note: This description may include information from UniProtKB.
Protein type: Protein kinase, AGC; Protein kinase, Ser/Thr (non-receptor); Kinase, protein; EC 2.7.11.1; AGC group; RSK family; MSK subfamily
Cellular Component: nucleoplasm; cytoplasm; nucleus
Molecular Function: protein serine/threonine kinase activity; protein binding; magnesium ion binding; ATP binding; protein kinase activity
Biological Process: axon guidance; nerve growth factor receptor signaling pathway; positive regulation of histone phosphorylation; histone phosphorylation; stress-activated MAPK cascade; toll-like receptor 3 signaling pathway; protein amino acid phosphorylation; toll-like receptor 10 signaling pathway; activation of NF-kappaB transcription factor; toll-like receptor 5 signaling pathway; regulation of transcription, DNA-dependent; inflammatory response; toll-like receptor 4 signaling pathway; epidermal growth factor receptor signaling pathway; MyD88-independent toll-like receptor signaling pathway; activation of CREB transcription factor; toll-like receptor 2 signaling pathway; MyD88-dependent toll-like receptor signaling pathway; negative regulation of cytokine production; toll-like receptor signaling pathway; innate immune response; positive regulation of histone acetylation; positive regulation of transcription from RNA polymerase II promoter; toll-like receptor 9 signaling pathway; negative regulation of transcription, DNA-dependent
