The kinase MK2 mediates proinflammatory cytokine production by regulating mRNA stability.1,2

  • MK2 is a serine threonine intracellular protein kinase, and the prime downstream substrate of p38MAPK, a signaling cascade that can be activated by stress and inflammatory stimuli.1-3
  • Activation of MK2 by p38 enables the stabilization of mRNA resulting in translation and production of pro-inflammatory cytokines such as TNFα and IL-17.1,2,4
  • TNFα and IL-17 have been implicated in the pathogenesis of ankylosing spondylitis (AS).4,5
