Sdha Gene Summary [Mouse]
Predicted to enable electron transfer activity; flavin adenine dinucleotide binding activity; and succinate dehydrogenase (quinone) activity. Predicted to contribute to succinate dehydrogenase activity. Predicted to be involved in mitochondrial electron transport, succinate to ubiquinone; nervous system development; and succinate metabolic process. Located in mitochondrial inner membrane and myelin sheath. Part of respiratory chain complex II (succinate dehydrogenase). Is active in mitochondrion. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and sensory organ. Human ortholog(s) of this gene implicated in Leigh disease; dilated cardiomyopathy 1GG; lung non-small cell carcinoma; mitochondrial complex II deficiency; and paraganglioma. Orthologous to human SDHA (succinate dehydrogenase complex flavoprotein subunit A). [provided by Alliance of Genome Resources, Apr 2025]

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 Sdha often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
