RSK2 is a member of the family of 90-kD ribosomal S6 kinases (1). These proteins are a class of serine/threonine kinases that are activated in response to various extracellular signals, including growth factors, polypeptide hormones and neurotransmitters (2). RSK2 plays a significant role in mediating extracellular signal-related kinase signal transduction. Mutations in RSK2 have been found to be associated with Coffin-Lowry syndrome (3). The N-terminal kinase of RSK2 is involved in substrate phosphorylation. The isolated N-terminal kinase of RSK2 (amino acids 1-360) is phosphorylated at Serine 227 by PDK1. Data indicate that full activation of RSK2 by growth factors requires the cooperation of extracellular signal-regulated kinase and PDK1 through phosphorylation of Serine 227, Serine 369, and Serine 386 (4).\n\nApplications: \nSuitable for use in Western Blotting, Immunoprecipitation. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:1000-1:2000\nImmunoprecipitation: 1:10\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only.
