Cox4i1 (human) recombinant (partial protein gst tag) 10 µg

Cytochrome c oxidase (COX) is the terminal enzyme of the mitochondrial respiratory chain. It is a multi-subunités 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 subunitéss. The mitochondrially-encoded subunitéss perform the electron transfer and proton pumping activities. The functions of the nuclear-encoded subunitéss are unknown but they may play a role in the regulation and assembly of the complex. This gene encodes the nuclear-encoded subunités IV isoform 1 of the human mitochondrial respiratory chain enzyme. It is located at the 3' of the NOC4 (neighbor of COX4) gene in a head-to-head orientation, and shares a promoter with it. [provided by RefSeq]
