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.

Multiple proteasome-interacting proteins assist the assembly of the yeast 19S regulatory particle.

The 26S proteasome is a highly conserved multisubunit protease that degrades ubiquitinated proteins in eukaryotic cells. The 26S proteasome consists of the proteolytic core particle (CP) and one or two 19S regulatory particles (RPs). Although the mechanisms of CP assembly are well described, the mechanism of RP assembly is largely unknown. Here, we show that four proteasome-interacting proteins (PIPs), Nas2/p27, ... [more]
