Gene

SDHB

Species
Homo sapiens
Symbol
SDHB
Name
succinate dehydrogenase complex iron sulfur subunit B
Synonyms
  • CWS2
  • FLJ92337
Biotype
protein coding gene
Automated Description
Enables succinate dehydrogenase (quinone) activity. Predicted to be involved in aerobic respiration and respiratory electron transport chain. Located in mitochondrion; nucleoplasm; and plasma membrane. Part of respiratory chain complex II (succinate dehydrogenase). Implicated in Carney-Stratakis syndrome; gastrointestinal stromal tumor; mitochondrial complex II deficiency; paraganglioma; and pheochromocytoma.
RGD Description
This tumor suppressor gene encodes the iron-sulfur protein subunit of the succinate dehydrogenase (SDH) enzyme complex which plays a critical role in mitochondria. The SDH enzyme complex is composed of four nuclear-encoded subunits. This enzyme complex converts succinate to fumarate which releases electrons as part of the citric acid cycle, and the enzyme complex additionally provides an attachment site for released electrons to be transferred to the oxidative phosphorylation pathway. The SDH enzyme complex plays a role in oxygen-related gene regulation through its conversion of succinate, which is an oxygen sensor that stabilizes the hypoxia-inducible factor 1 (HIF1) transcription factor. Sporadic and familial mutations in this gene result in paragangliomas, pheochromocytoma, and gastrointestinal stromal tumors, supporting a link between mitochondrial dysfunction and tumorigenesis. Mutations in this gene are also implicated in nuclear type 4 mitochondrial complex II deficiency. [provided by RefSeq, Jun 2022]
