Application Abreviews Notes
IHC-P 1/500 - 1/2000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB 1/2000 - 1/10000. Predicted molecular weight: 84 kDa.
  • Application notesIs unsuitable for IP.
  • Target

    • FunctionSerine/threonine kinase that may play a role in mediating the growth-factor and stress induced activation of the transcription factor CREB.
    • Tissue specificityExpressed in many tissues, highest levels in skeletal muscle.
    • Involvement in diseaseDefects in RPS6KA3 are the cause of Coffin-Lowry syndrome (CLS) [MIM:303600]; an X-linked dominant disorder characterized by severe mental retardation with facial and digital dysmorphisms, and progressive skeletal deformations.
    • Sequence similaritiesBelongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily.
      Contains 1 AGC-kinase C-terminal domain.
      Contains 2 protein kinase domains.
    • Post-translational
      Autophosphorylated on Ser-386, as part of the activation process.
      Ser-227 phosphorylation promotes Ser-386 phosphorylation and leads to basal activation. Full activation by growth factors requires additional phosphorylation on Ser-369.
