Protein

Cytochrome c iso-1

Gene

CYC1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain.

Miscellaneous

Post-translational modificationi

Binds 1 heme group per subunit.
Methylation may enhance its transport into mitochondria. Methylation occurs in fungi, plants, and some protozoa, but not in animals. The precise role of methylation at Lys-79 is unknown, but it seems to preclude pro-apoptotic activity, possibly by lowering affinity for APAF1.4 Publications
