| Introduction | The 90 kDa ribosomal S6 kinases (RSK1-4) are a family of widely expressed Ser/Thr kinases characterized by two nonidentical, functional kinase domains and a carboxy-terminal docking site for extracellular signal-regulated kinases (ERKs). 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 stimulation, 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, resulting in full enzymatic activation of p90RSK. Antibodies against these phosphorylation sites are useful for understanding the kinetics and regulation of p90RSK activation. |
