    basic FUNCTION
  • succinate-ubiquinone oxidoreductase, catalyzing the seventh step of the citric acid cycle (tricarboxylic acid cycle)
  • a crucial dosage-dependent role for SDHA, SDHB in oxygen homeostasis
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism organic acid
    signaling
    a component
  • complex II of mitochondrial respiratory chain, oxidative phosphorylation, (OXPHOS)
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • SDHA and SDHB interacted specifically with SIRT3 (SIRT3 may be an important physiological regulator of SDH activity)
  • CERS5 and SDHB interaction may synergistically affect transcriptional regulation of TP53 and CDKN1A
