UQCRFS1

Ubiquinol-cytochrome c reductase, Rieske iron-sulfur polypeptide 1, also known as UQCRFS1, is a is_associated_with::protein which in humans is encoded by the UQCRFS1 is_associated_with::gene.

UQCRFS1 is a subunit of the respiratory chain protein Ubiquinol Cytochrome c Reductase (UQCR, is_associated_with::Complex III or Cytochrome bc1 complex), which consists of the products of one mitochondrially encoded gene:


 * MTCYTB (mitochondrial is_associated_with::cytochrome b)

and ten nuclear genes:


 * is_associated_with::UQCRC1, is_associated_with::UQCRC2, is_associated_with::Cytochrome C1, UQCRFS1 (this protein, a type of is_associated_with::Rieske protein), is_associated_with::UQCRB, ("11kDa protein"), is_associated_with::UQCRH (cyt c1 Hinge protein), is_associated_with::UCRC ("cyt. c1 associated protein"), and ("Rieske-associated protein").

After processing the cleaved leader sequence of the iron-sulfur protein is retained as subunit 9, giving 11 subunits from 10 genes.
