Background :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 Thr573 (p90RSK1 numbering) located within the C-terminal kinase domain and Thr359/Ser363 in the linker region between the two kinase domains. Phosphorylation of Thr573 within the activation loop of the p90RSK C-terminal kinase domain promotes activation and directs phosphorylation of Ser380 within the hydrophobic stretch of the linker region. The phosphorylated p90RSK Ser380 acts as a docking site for the constitutively active Ser/Thr kinase PDK1, which in turn phosphorylates Ser221 within the N-terminal kinase domain activation loop, resulting in full enzymatic activation of the p90RSK. Antibodies against these phosphorylation sites are useful for understanding the kinetics and regulation of p90RSK activation.For more information regarding the phospho-regulatory sites within each RSK isoform, including more information regarding the seminal studies demonstrating the complex phosphorylation cascades involved, please see the references herein and PhosphoSitePlus.
