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.

Respiratory Chain Supercomplexes associate with the Cysteine Desulfurase Complex of the Iron-Sulfur Cluster Assembly Machinery.

Boettinger L, Martensson CU, Song J, Zufall N, Wiedemann N, Becker T

Mitochondria are the powerhouses of eukaryotic cells. The activity of the respiratory chain complexes generates a proton gradient across the inner membrane, which is used by the F1FO-ATP synthase to produce ATP for cellular metabolism. In baker's yeastSaccharomyces cerevisiaethe cytochromebc1complex (complex III) and cytochromecoxidase (complex IV) associate in respiratory chain supercomplexes. Iron-sulfur clusters (ISC) form reactive centers of respiratory chain ... [more]

Negative Genetic
Negative Genetic

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
