Genes affected

SURF2 (HGNC:11475): (surfeit 2) This gene shares a bidirectional promoter with surfeit 1 (SURF1; GeneID: 6834), which is located on the opposite strand. It encodes a conserved protein that is expressed in a variety of tissues. [provided by RefSeq, Jul 2013]

SURF2 links:

SURF1 (HGNC:11474): (SURF1 cytochrome c oxidase assembly factor) This gene encodes a protein localized to the inner mitochondrial membrane and thought to be involved in the biogenesis of the cytochrome c oxidase complex. The protein is a member of the SURF1 family, which includes the related yeast protein SHY1 and rickettsial protein RP733. The gene is located in the surfeit gene cluster, a group of very tightly linked genes that do not share sequence similarity, where it shares a bidirectional promoter with SURF2 on the opposite strand. Defects in this gene are a cause of Leigh syndrome, a severe neurological disorder that is commonly associated with systemic cytochrome c oxidase deficiency. [provided by RefSeq, Jul 2008]
