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.

The β-catenin E3 ubiquitin ligase SIAH-1 is regulated by CSN5/JAB1 in CRC cells.

Jumpertz S, Hennes T, Asare Y, Vervoorts J, Bernhagen J, Schuetz AK

COP9 signalosome subunit 5 (CSN5) plays a decisive role in cellular processes such as cell cycle regulation and apoptosis via promoting protein degradation, gene transcription, and nuclear export. CSN5 regulates cullin-RING-E3 ligase (CRL) activity through its deNEDDylase function. It is overexpressed in several tumor entities, but its role in colorectal cancer (CRC) is poorly understood. Wnt/β-catenin signaling is aberrant in ... [more]
