General annotation (Comments)

Function

This is a component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain. The core protein 2 is required for the assembly of the complex By similarity.

Subunit structure

Fungi bc1 complex contains 10 subunits; 3 respiratory subunits, 2 core proteins and 5 low-molecular weight proteins By similarity.

Subcellular location

Mitochondrion inner membrane By similarity.

Sequence similarities

Belongs to the peptidase M16 family. UQCRC2/QCR2 subfamily.

Caution

Does not seem to have a protease activity as it lack the zinc-binding site.
