    Protocol

    Specificity / Sensitivity

    Phospho-p90RSK (Ser380) Antibody detects endogenous levels of p90RSK only when phosphorylated at Ser380. This antibody does not recognize p90RSK phosphorylated at other sites. This antibody shows some cross-reactivity with RSK2 and RSK3 when phosphorylated at the homologous serine residues.

    Human, Mouse, Rat, Monkey

    The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.

    Species predicted to react based on 100% sequence homology:

    Hamster, Dog

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser380 of human p90RSK. 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).
