Description
Imported from IPR045214

This entry includes SURF1 and Shy1 proteins. The surfeit locus 1 gene (SURF1 or surf-1) encodes a conserved protein of about 300 amino-acid residues that seems to be involved in the biogenesis of cytochrome c oxidase
[1]
. Vertebrate SURF1 is evolutionary related to yeast protein Shy1, which is a mitochondrial inner membrane protein required for assembly of cytochrome c oxidase
[4]
. There seems to be two transmembrane regions in these proteins, one in the N-terminal, the other in the C-terminal.

Defects in SURF1 are a cause of Leigh syndrome (LS). LS is a severe neurological disorder characterised by bilaterally symmetrical necrotic lesions in subcortical brain regions that is commonly associated with systemic cytochrome c oxidase (COX) deficiency
[1, 2, 3]
.

The surfeit locus gene SURF4 (or surf-4) encodes a conserved integral eukaryotic membrane protein of about 270 to 300 amino-acid residues that seems to be located in the endoplasmic reticulum
[5]
.
