Succinate dehydrogenase complex assembly factor 2, formerly known as SDH5 and also known as SDH assembly factor 2 or SDHAF2 is a protein that in humans is encoded by the SDHAF2 gene. This gene encodes a mitochondrial protein needed for the flavination of a succinate dehydrogenase complex subunit required for activity of the complex. Mutations in this gene are associated with pheochromocytoma and paraganglioma.

== Structure == SDHAF2 is located on the q arm of chromosome 11 in position 12.2 and spans 16,642 base pairs. The SDHAF2 gene produces a 6.7 kDa protein composed of 65 amino acids. This highly conserved protein is a cofactor of flavin adenine dinucleotide (FAD). The structure represents a five-helix bundle with a region of well-defined conserved surface residues. This conserved region includes a negatively charged periphery and a positively charged surface, and a patch that is hydrophobic. The region is located in α-helices I, II, and the connecting band.
