Polyclonal Rabbit Affinity Purified B
MSK1 is a dual kinase domain protein that acts downstream of the ERK1/2 and p38 MAPK signalling pathways. MSK1 phosphorylate the transcription factors CREB and ATF1, and the chromatin proteins histone H3 and HMGN1 in response to either mitogenic stimulation or cellular stress. MSK1 activity is tightly regulated in cells, and activation requires its phosphorylation by either ERK1/2 or p38alpha. This result in activation of the C-terminal kinase domain, which then phosphorylates further sites in MSK1, leading to the activation of the N-terminal kinase domain and phosphorylation of substrates. The protein contains two complete nonidentical protein kinase domains. The protein is widely expressed in human brain, heart, and placenta. Human MSK1 gene is mapped to chromosomal region 14q31-q32.1.
