      Biological Information
      SourceExpressed by baculovirus in Sf21 insect cells
      Specific ActivityFor Specific Activity data, refer to the Certificate of Analysis for individual lots of this enzyme.
      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains 2 non-identical kinase catalytic domains and phosphorylates various substrates, including members of the mitogen-activated kinase (MAPK) signalling pathway. The activity of this protein has been implicated in controlling cell growth and differentiation. Mutations in this gene have been associated with Coffin-Lowry syndrome (CLS).

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P51812 # Serine/threonine kinase that may play a role in mediating the growth-factor and stress induced activation of the transcription factor CREB.
      COFACTOR: Magnesium (By similarity).
      SIZE: 740 amino acids; 83736 Da
      SUBUNIT: Forms a complex with either ERK1 or ERK2 in quiescent cells. Transiently dissociates following mitogenic stimulation (By similarity).
      TISSUE SPECIFICITY: Expressed in many tissues, highest levels in skeletal muscle.
      PTM: Autophosphorylated on Ser-386, as part of the activation process (By similarity). & Ser-227 phosphorylation promotes Ser-386 phosphorylation and leads to basal activation. Full activation by growth factors requires additional phosphorylation on Ser-369 (By similarity).
      DISEASE: SwissProt: P51812 # Defects 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.
      SIMILARITY: SwissProt: P51812 ## Belongs 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.
