BCS1

bifunctional AAA family ATPase chaperone/translocase BCS1, L000000164, YDR375C
Protein translocase and chaperone required for Complex III assembly; member of the AAA ATPase family; forms a homo-oligomeric complex in the mitochondrial inner membrane that translocates the C-terminal domain of Rip1p from the matrix across the inner membrane, and then delivers it to an assembly intermediate of respiratory Complex III in an ATP-dependent reaction; also required for assembly of the Qcr10p subunit; mutations in human homolog BCS1L linked to neonatal diseases
Saccharomyces cerevisiae (S288c)

QCR6

COR3, UCR6, ubiquinol--cytochrome-c reductase subunit 6, L000001546, YFR033C
Subunit 6 of the ubiquinol cytochrome-c reductase complex; the complex, also known as the cytochrome bc(1) complex or Complex III, is a component of the mitochondrial inner membrane electron transport chain; highly acidic protein; required for maturation of cytochrome c1; may be loosely associated with the complex since it is easily released into the intermembrane space
Saccharomyces cerevisiae (S288c)

Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

Bcs1p, an AAA-family member, is a chaperone for the assembly of the cytochrome bc(1) complex.

Cruciat CM, Hell K, Foelsch H, Neupert W, Stuart RA

Bcs1p, a mitochondrial protein and member of the conserved AAA protein family, is involved in the biogenesis of the cytochrome bc(1) complex. We demonstrate here that Bcs1p is directly required for the assembly of the Rieske FeS and Qcr10p proteins into the cytochrome bc(1) complex. Bcs1p binds to a precomplex in the assembly pathway of the cytochrome bc(1) complex. Binding ... [more]
