CST, 9348S, Phospho-RSK3 (Thr356/Ser360) Antibody

Polyclonal Antibody for studying RSK2 (Thr365/Ser369) phosphate/RSK3 (Thr356/Ser360) phosphate/RSK1 (Thr359/Ser363) phosphate. Validated for Western Blotting,Immunoprecipitation. Highly specific and rigorously validated in-house, Phospho-RSK3 (Thr356/Ser360) Antibody (CST #9348) is ready to ship. Product Usage Information Western Blotting: 1:1000 Immunoprecipitation: 1:50 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting, Immunoprecipitation Specificity / Sensitivity Phospho-RSK3 (Thr356/Ser360) Antibody detects endogenous levels of RSK3 only when phosphorylated at threonine 356 and serine 360. This antibody does not recognize RSK3 phosphorylated at other sites. This antibody shows some cross-reactivity with RSK1 and RSK2 when phosphorylated at the homologous sites. Species Reactivity: Human, Mouse, Rat, Monkey Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr356/Ser360 of human RSK3. Antibodies are purified by protein A and peptide affinity chromatography. 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 (1) and a carboxy-terminal docking site for extracellular signal-regulated kinases (ERKs) (2). Several sites both within and outside of the RSK kinase domain, including Ser380, Thr359, Ser363, and Thr573, are important for kinase activation (3). 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 (3). crazy Alternate Names 90 kDa ribosomal protein S6 kinase 1; 90 kDa ribosomal protein S6 kinase 2; 90 kDa ribosomal protein S6 kinase 3; CLS; dJ590P13.1 (ribosomal protein S6 kinase, 90kD, polypeptide 1); epididymis secretory sperm binding protein; HU-1; HU-2; HU-3; Insulin-stimulated protein kinase 1; ISPK-1; ISPK1; KS6A1; KS6A2; KS6A3; MAP kinase-activated protein kinase 1a; MAP kinase-activated protein kinase 1b; MAP kinase-activated protein kinase 1c; MAPK-activated protein kinase 1a; MAPK-activated protein kinase 1b; MAPK-activated protein kinase 1c; MAPKAP kinase 1a; MAPKAP kinase 1b; MAPKAP kinase 1c; MAPKAPK-1a; MAPKAPK-1b; MAPKAPK-1c; MAPKAPK1; MAPKAPK1A; MAPKAPK1B; MAPKAPK1C; mental retardation, X-linked 19; mitogen-activated protein kinase-activated protein kinase 1C; MRX19; p90-RSK 1; p90-RSK 2; p90-RSK 3; p90-RSK2; p90-RSK3; p90RSK; p90RSK1; p90RSK2; p90RSK3; p90S6K; pp90RSK2; pp90RSK3; ribosomal protein S6 kinase A1; ribosomal protein S6 kinase A2; ribosomal protein S6 kinase A3; ribosomal protein S6 kinase alpha 1; ribosomal protein S6 kinase alpha 2; Ribosomal protein S6 kinase alpha-1; Ribosomal protein S6 kinase alpha-2; Ribosomal protein S6 kinase alpha-3; ribosomal protein S6 kinase, 90kDa, polypeptide 1; ribosomal protein S6 kinase, 90kDa, polypeptide 2; ribosomal protein S6 kinase, 90kDa, polypeptide 3; Ribosomal S6 kinase 1; Ribosomal S6 kinase 2; Ribosomal S6 kinase 3; RPS6KA1; RPS6KA2; RPS6KA3; RSK; RSK-1; RSK-2; RSK-3; RSK1; RSK2; RSK3; S6K-alpha; S6K-alpha 1; S6K-alpha-1; S6K-alpha-2; S6K-alpha-3; S6K-alpha2; S6K-alpha3 Specification REACTIVITY: H M R Mk SENSITIVITY: Endogenous MW (kDa): 90 SOURCE: Rabbit
