Several sites both within and outside of the RSK kinase domain, including Ser380, Thr359, Ser363, and Thr573, are important for kinase activation. RSK1-3 are activated via coordinated phosphorylation by MAPKs, autophosphorylation, and phosphoinositide-3-OH kinase (PI3K) in response to many growth factors, polypeptide hormones, and neurotransmitters. Upon mitogenic stimμlation, p44\/42 Erk1\/2 and Erk5 MAP kinases cooperatively phosphorylate p90RSK at Thr573 (p90RSK1 numbering) located within the C-terminal kinase domain and at Thr359\/Ser363 in the linker region between the two kinase domains. Phosphorylation at Thr573 within the activation loop of the p90RSK C-terminal kinase domain promotes activation and directs phosphorylation at Ser380 within the hydrophobic stretch of the linker region. When phosphorylated, Ser380 acts as a docking site for the constitutively active Ser\/Thr kinase PDK1, which in turn phosphorylates p90RSK at Ser221 within the N-terminal kinase domain activation loop, resμlting in fμll enzymatic activation of p90RSK. Antibodies against these phosphorylation sites are usefμl for understanding the kinetics and regμlation of p90RSK activation.
