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 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, resμlting in fμll enzymatic activation of the p90RSK. Antibodies against these phosphorylation sites are usefμl for understanding the kinetics and regμlation of p90RSK activation.For more information regarding the phospho-regμlatory 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.\u003c\/p\u003e\n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Hamster\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB, IHC, IF\/ICC, IP\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: MAPKAPK1C, RSK3, Ribosomal protein S6 kinase alpha-2, S6K-alpha-2, 90 kDa ribosomal protein S6 kinase 2, p90-RSK 2, p90RSK2, MAP kinase-activated protein kinase 1c, MAPK-activated protein kinase 1c, MAPKAP kinase 1c, MAPKAPK-1c, Ribosomal S6 kinase 3, RSK-3, pp90RSK3\u003c\/p\u003e\n\n\u003cp\u003eClonality: Monoclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Unmodification\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: A synthetic peptide of human RSK3\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB (1\/500 - 1\/1000), IHC (1\/50 - 1\/100), IF\/ICC (1\/50 - 1\/100), IP (1\/10 - 1\/50)\u003c\/p\u003e\n\n\u003cp\u003ePurification: The antibody was purified by immunogen affinity chromatography.\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: Recognizes endogenous levels of RSK3 protein.\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: ~ 83 kDa\u003c\/p\u003e\n\n\u003cp\u003ePathway: Jak Stat: IL-6 Receptor Signaling, Cell Cycle G2 M DNA Damage Signaling Pathway, Regμlation of Apoptosis, MAPK Erk in Growth and Differentiation Pathway, Inhibition of Apoptosis, Mitochondrial Control of Apoptosis, MTOR signaling\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
