COX5B - cytochrome c oxidase subunit 5B Gene

Also known as COXVB

About COX5B

Summary

Cytochrome C oxidase (COX) is the terminal Enzyme of the mitochondrial respiratory chain. It is a multi-subunit Enzyme complex that couples the transfer of electrons from cytochrome c to molecular oxygen and contributes to a proton electrochemical gradient across the inner mitochondrial membrane. The complex consists of 13 mitochondrial- and nuclear-encoded subunits. The mitochondrially-encoded subunits perform the electron transfer and proton pumping activities. The functions of the nuclear-encoded subunits are unknown but they may play a role in the regulation and assembly of the complex. This gene encodes the nuclear-encoded subunit Vb of the human mitochondrial respiratory chain Enzyme. [provided by RefSeq, Jul 2008]
