    basic FUNCTION
  • protein phosphatase 2A, catalytic subunit
  • potential modulation of phosphorylase-b-kinase, casein kinase 2 and others
  • function as tumor suppressor protein, and important physiological regulator of cell growth and of cellular stress signaling (Lammers 2007)
  • act as a negative regulator of NFKB1-mediated inflammatory signaling
    • CELLULAR PROCESS

  • Fe
  • Mn
    • protein
  • IGBP1
  • PME1
  • PRKACA destabilizes PP2CB upon inflammatory stimuli via phosphorylation of Ser-195 in PP2CB
  • PPP2CB, a catalytic subunit of protein phosphatase 2A, could interact directly with GADD45A
