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. This protein may mediate formation of the complex between cytochromes c and c1.

Subunit structure

The bc1 complex contains 11 subunits: 3 respiratory subunits (cytochrome b, cytochrome c1 and Rieske/UQCRFS1), 2 core proteins (UQCRC1/QCR1 and UQCRC2/QCR2) and 6 low-molecular weight proteins (UQCRH/QCR6, UQCRB/QCR7, UQCRQ/QCR8, UQCR10/QCR9, UQCR11/QCR10 and a cleavage product of Rieske/UQCRFS1).

Subcellular location

Mitochondrion inner membrane; Peripheral membrane protein; Matrix side.

Sequence similarities

Belongs to the peptidase M16 family. UQCRC1/QCR1 subfamily.

Caution

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