    text
  • anchored in the mitochondrial membrane
  • targeted to the outer membrane of mitochondria by an N-terminal mitochondrial-localization sequence
  • basic FUNCTION
  • KEAP1-dependent ubiquitination of PGAM5 results in proteasome-dependent degradation of PGAM5
  • enzyme of intermediary metabolism that converts 3-phosphoglycerate to 2-phosphoglycerate in glycolysis
  • is the convergent point for multiple necrosis pathways
  • mitochondrial phosphatase that functions in programmed necrosis (necroptosis)
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • forms a ternary complex containing both KEAP1 and NFE2L2, in which the dimeric KEAP1 protein simultaneously binds both PGAM5 and NFE2L2 through their conserved E(S/T)GE motifs
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • lacking PGAM activity and instead associates with the MAP kinase kinase kinase MAP3K5 and acting as a specific protein Ser/Thr phosphatase that activates MAP3K5 by dephosphorylation of inhibitory sites
  • dephosphorylates and activates mitochondrial fission protein DNM1L
  • BCL2L1, interacts with and inhibits PGAM5, a mitochondrially localized phosphatase, to prevent the dephosphorylation of FUNDC1 at serine 13 (Ser13), which activates hypoxia-induced mitophagy
