Ribosomal protein S6 kinases (RSK) are a family of broadly expressed serine/threonine kinases activated in response to mitogenic stimuli, including tumor-promoting growth factors and phorbol esters. RSKs are positioned downstream of the Raf-MEK-ERK signal transduction pathway, and are directly phosphorylated by ERK1 and ERK2extracellular kinases. Active RSKs appear to play a significant role in transcriptional regulation, translocation to the nucleus, and phosphorylation of c-Fos and CREBs.
Current models suggest that RSK activation requires a binding of active ERK1/2 to a docking site at the carboxyl end of RSK. ERK moored to RSK1 phosphorylate at several sites, including the CTD activation loop (carboxyl-terminal kinase domain). The CTD autophosphorylates Serine 380, a site in the central hydrophobic region.
The AlphaLISA® SureFire® Ultra™ p-RSK1 (Ser380) assay is a sandwich immunoassay for the quantitative detection of phospho-RSK1 (phosphorylated on Ser380) in cellular lysates, using Alpha Technology.
