	intracellular,cytoplasm,organelle,membrane

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
