Systematic name YEL024W
Gene name RIP1
Feature type ORF, Verified
Coordinates Chr V:107260..107907
Primary SGDID S000000750

Description of YEL024W: Ubiquinol-cytochrome-c reductase, a Rieske iron-sulfur protein of the mitochondrial cytochrome bc1 complex; transfers electrons from ubiquinol to cytochrome c1 during respiration; during import, Rip1p is first imported into the mitochondrial matrix where it is processed, acquires its Fe-S cluster, and is folded, then is translocated into the inner membrane by the action of a homo-oligomer of Bcs1p, and finally is delivered by Bcs1p to Complex III for assembly[1][2][3][4]
