Anti-ACN9 antibodies enable researchers to detect and measure the ACN9 antigen in biological samples. This target is a reported synonym of the SDHAF3 gene, which encodes succinate dehydrogenase complex assembly factor 3. This protein is known to function in metabolic processes, among other biological roles. The human version of ACN9 has a canonical amino acid length of 125 residues and a protein mass of 14.7 kilodaltons. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. ACN9 is a member of the Complex I LYR protein family.
