Ubiquinol-cytochrome c reductase complex (7.2 kD), also known as UCRC or UQCR10, is a human

gene In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protei ...

UQCRC1 Cytochrome b-c1 complex subunit 1, mitochondrial is a protein that in humans is encoded by the ''UQCRC1'' gene. Its gene product is a subunit of the respiratory chain protein Ubiquinol Cytochrome c Reductase (UQCR, Complex III or Cytochrome bc1 ...

UQCRC2 Cytochrome b-c1 complex subunit 2, mitochondrial (UQCRC2), also known as QCR2, UQCR2, or MC3DN5 is a protein that in humans is encoded by the ''UQCRC2'' gene. The product of ''UQCRC2'' is a subunit of the respiratory chain protein Ubiquinol Cyto ...

Cytochrome c1 Cytochrome C1 (also known as Complex III subunit 4) is a protein encoded by the '' CYC1'' gene. Cytochrome is a heme-containing subunit of the cytochrome b-c1 complex, which accepts electrons from Rieske protein and transfers electrons to cytoc ...
