  • Product nameAnti-MAPKAP Kinase 2 (phospho T334) antibody [EPR992Y]
    See all MAPKAP Kinase 2 primary antibodies
  • Description
    Rabbit monoclonal [EPR992Y] to MAPKAP Kinase 2 (phospho T334)
  • SpecificityThe immunogen sequence used to produce ab51018 is 90% identical to the corresponding region of MAPKAP Kinase 3, therefore ab51018 may cross react with human MAPKAP Kinase 3 but this has not been confirmed.

  • Target

    • FunctionIts physiological substrate seems to be the small heat shock protein (HSP27/HSP25). In vitro can phosphorylate glycogen synthase at 'Ser-7' and tyrosine hydroxylase (on 'Ser-19' and 'Ser-40'). This kinase phosphorylates Ser in the peptide sequence, Hyd-X-R-X(2)-S, where Hyd is a large hydrophobic residue (By similarity). Mediates both ERK and p38 MAPK/MAPK14 dependent neutrophil responses. Participates in TNF alpha-stimulated exocytosis of secretory vesicles in neutrophils. Plays a role in phagocytosis-induced respiratory burst activity.
    • Tissue specificityExpressed in all tissues examined.
    • Sequence similaritiesBelongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family.
      Contains 1 protein kinase domain.
    • Post-translational
      Phosphorylated and activated by MAP kinase.
