Specificity / Sensitivity
Phospho-p90RSK (Ser380) (9D9) Rabbit mAb detects endogenous levels of p90RSK only when phosphorylated at Ser380. It shows some cross-reactivity with RSK2 and RSK3 when phosphorylated at the homologous serine residues.
Source / Purification
Monoclonal antibodies are produced by immunizing rabbits with a synthetic phospho-peptide (KLH-coupled) corresponding to residues surrounding Ser380 of human p90RSK.
Western Blotting
Western blot analysis of extracts from untreated or TPA-treated 293 and NIH/3T3 cells using Phospho-p90RSK (Ser380) (9D9) Rabbit mAb.
Background
The 90 kDa ribosomal S6 kinases (RSK1?4) are a family of widely expressed serine/threonine kinases characterized by two nonidentical, functional kinase domains (1) and a C-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, by autophosphorylation, and by phosphoinositide-3-OH kinase (PI3K) in response to many growth factors, polypeptide hormones and neurotransmitters (3).
