Sdhd Gene Summary [Mouse]
Enables succinate dehydrogenase (quinone) activity. Acts upstream of or within cellular response to hypoxia and regulation of catecholamine secretion. Located in mitochondrion. Part of respiratory chain complex II (succinate dehydrogenase). Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in Carney-Stratakis syndrome; mitochondrial complex II deficiency; and paraganglioma. Orthologous to human SDHD (succinate dehydrogenase complex subunit D).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Sdhd often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
