Cytochrome b-c1 complex subunit 2, mitochondrial (P07257)

Identification
NameCytochrome b-c1 complex subunit 2, mitochondrial
Synonyms
  • Complex III subunit 2
  • Core protein II
  • Ubiquinol-cytochrome-c reductase complex core protein 2
Gene NameQCR2
Enzyme ClassNot Available
Biological Properties
General FunctionInvolved in metalloendopeptidase activity
Specific FunctionComponent of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain that generates an electrochemical potential coupled to ATP synthesis. The complex couples electron transfer from ubiquinol to cytochrome c. QCR2 is required for the assembly of the complex
