UCR_14kD

UCR_14kD
PFAM accession number:PF02271
Interpro abstract (IPR003197):

Cytochrome b-c1 complex subunit 7 (QCR7, also known as UQCRB) 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. QCR7 is involved in redox-linked proton pumping [ (PUBMED:2170131) (PUBMED:6319130) (PUBMED:11556808) ].

GO process:mitochondrial electron transport, ubiquinol to cytochrome c (GO:0006122)
GO component:mitochondrial respiratory chain complex III (GO:0005750)
