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.

Histidine-tagged ubiquitin substitutes for wild-type ubiquitin in Saccharomyces cerevisiae and facilitates isolation and identification of in vivo substrates of the ubiquitin pathway.

Ling R, Colon E, Dahmus ME, Callis J

A general method for purification of any substrate of the ubiquitin pathway, the major eukaryotic proteolytic pathway, should utilize the common characteristic of covalent linkage of ubiquitin to substrate lysyl residues. The utility of a N-terminal histidine-tagged ubiquitin (HisUb) for in vivo conjugation and isolation of ubiquitinated proteins by metal chelation chromatography is conditioned by the requirement that HisUb conjugate ...
