• Product name

    Anti-MK2 (phospho T334) antibody
    See all MK2 primary antibodies
  • Description

    Rabbit polyclonal to MK2 (phospho T334)
  • Host species

  • Specificity

    ab131504 detects endogenous levels of MK2 only when phosphorylated at threonine 334. The immunogen sequence used to produce ab131504 is 90% identical to the corresponding region of MAPKAP Kinase 3MK3, therefore ab131504 may cross react with human MK3 but this has not been confirmed.

  • Tested applications

  • Function

    Its 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 specificity

    Expressed in all tissues examined.
  • Sequence similarities

    Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family.
    Contains 1 protein kinase domain.
  • Post-translational

    Phosphorylated and activated by MAP kinase.
