From the abstract: "Leigh Syndrome (LS) is the most common early-onset,
progressive mitochondrial encephalopathy usually leading to early death.
The single most prevalent cause of LS is occurrence of mutations in the
SURF1 gene, and LS(Surf1) patients show a ubiquitous and specific
decrease in the activity of mitochondrial respiratory chain complex IV
(cytochrome c oxidase, COX). SURF1 encodes an inner membrane
mitochondrial protein involved in COX assembly. We established a Drosophila melanogaster model of LS based on the post-transcriptional silencing of CG9943, the Drosophila
homolog of SURF1. ... We conclude that
Surf1 is essential for COX activity and mitochondrial function in D.
melanogaster, thus providing a new tool that may help clarify the
pathogenic mechanisms of LS."
