SDHB

Complex II of the respiratory chain, which is specifically involved in the oxidation of succinate, carries electrons from FADH to CoQ. The complex is composed of four nuclear-encoded subunits and is localized in the mitochondrial inner membrane. The iron-sulfur subunit is highly conserved and contains three cysteine-rich clusters which may comprise the iron-sulfur centers of the enzyme. Sporadic and familial mutations in this gene result in paragangliomas and pheochromocytoma, and support a link between mitochondrial dysfunction and tumorigenesis.

Predicted location

Intracellular

Single cell type specificity

Cell type enhanced (Proximal tubular cells, Cardiomyocytes)

Immune cell specificity

Low immune cell specificity

Cell line specificity

Low cell line specificity

Interaction

Component of complex II composed of four subunits: the flavoprotein (FP) SDHA, iron-sulfur protein (IP) SDHB, and a cytochrome b560 composed of SDHC and SDHD (By similarity). Interacts with SDHAF1; the interaction is required for iron-sulfur cluster incorporation into SDHB (PubMed:26749241). (Microbial infection) Interacts with JC virus small t antigen.
