Ubiquinol-cytochrome c reductase, Rieske iron-sulfur polypeptide 1, also known as UQCRFS1, Rieske iron-sulfur (Fe-S) protein, Cytochrome b-c1 complex subunit 5, or Complex III subunit 5 is a
protein which in humans is encoded by the UQCRFS1gene.[5] UQCRFS1 is a subunit of the respiratory chain protein
Ubiquinol Cytochrome c Reductase (UQCR,
Complex III or Cytochrome bc1 complex), which consists of the products of one mitochondrially encoded gene,
MTCYTB (mitochondrial
cytochrome b) and ten nuclear genes
UQCRC1,
UQCRC2,
Cytochrome C1, UQCRFS1 (this protein, a type of
Rieske protein),
UQCRB,UQCRQ ("11kDa protein"),
UQCRH (cyt c1 Hinge protein),
UCRC ("cyt. c1 associated protein"), and UQCR ("Rieske-associated protein").[6]
UQCRFS1 is located on the
q arm of
chromosome 19 in position 12, has 2
exons, and spans 5,969 base pairs.[5] The UQCRFS1 gene produces a 29.7 kDa protein composed of 274
amino acids.[7][8] UQCRFS1 is a subunit of the respiratory chain protein
Ubiquinol Cytochrome c Reductase (UQCR,
Complex III or Cytochrome bc1 complex). The structure of the complex is a symmetric homodimer composed of one
mitochondrial genome encoded cytochrome b subunit and ten other nucleus encoded subunits.[9] The primary structure of UQCRFS1 from cDNA analysis is composed of a 78 amino acid long
N-terminal extension sequence.[10]

The UQCRFS1 gene has been shown to be involved in
carcinogenesis of some cancers. It is mainly associated with more aggressive
tumors, and results in the development of more aggressive
phenotypes of
breast cancers. The association was found with a grade 3 amplification of the UQCRFS1 gene.[13] In addition,
Acute myeloid leukemia (AML) has been found to be associated with the amplification of UQCRFS1 gene.[14] In contrast, UQCRFS1 and complex III has been absent in renal cell
carcinoma, though the mechanism is unknown.[15]
