Background

MSK1, a mitogen and stress activated protein kinase, is activated by Erk as well as p38 MAPK in response to growth factors and cellular stress, respectively. MSK1 resembles RSK because it has two kinase domains connected by a regulatory linker region. Phosphorylation of RSK1 at Ser364 and Ser381 is critical for RSK1 activity. These sites are analogous to Ser360 and Ser376 of MSK1, which may be important for MSK1 activity as well.
