C35D10.5 encodes the C. elegans homolog of vertebrate and budding yeast CBP3, a ubiquinol-cytochrome c reductase complex chaperone; by homology, the product of C35D10.5 is predicted to function as a mitochondrial enzyme-specific chaperone that is required for the assembly of ubiquinol-cytochrome c reductase; loss of C35D10.5 activity via RNAi results in embryos that contain a short pharynx and rounded mouth.
Predicted to be involved in mitochondrial respiratory chain complex III assembly. Predicted to be located in mitochondrion. Is an ortholog of human UQCC1 (ubiquinol-cytochrome c reductase complex assembly factor 1).
