Protein
Cytochrome b translational activator protein CBS1, mitochondrial
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
mRNA-specific translational activator of cytochrome b. The cytochrome b (COB) leader RNA may represent the target sequence for CBS1 and CBS2, tethering the COB mRNA to the inner mitochondrial membrane, where cotranslational insertion of cytochrome b into the membrane can occur.
