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.

Characterization of the deubiquitinating activity of USP19 and its role in endoplasmic reticulum-associated degradation.

Lee JG, Kim W, Gygi S, Ye Y

Deubiquitinating enzymes (DUBs) regulate various cellular processes ranging from protein degradation to cellular signaling. USP19, the only DUB containing a carboxyl-terminal transmembrane domain, was proposed to function in endoplasmic reticulum-associated degradation (ERAD). Here we characterize the function and regulation of USP19. We identify Hsp90 as a specific partner that binds the catalytic domain of USP19 to promote substrate association. Intriguingly, ... [more]
