Phospho-MSK1 (Thr581) rabbit mAb FITC conjugate Antibody

MSK1 (mitogen and stress activated protein kinase 1, phospho MSK1) is activated by Erk in response to growth factors and by and p38 in response to cellular stress (1) . MSK1 is similar to RSK1 in that it has two kinase domains and a connecting regulatory linker region (2) . S364/S381 phosphorylation activates RSK1 (3), which is analogous to residues S360 and S376 of MSK1, which may be important for phospho MSK1 activity.
