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.

Coronin7 forms a novel E3 ubiquitin ligase complex to promote the degradation of the anti-proliferative protein Tob.

Watanabe M, Suzuki T, Kim M, Abe Y, Yoshida Y, Sugano S, Yamamoto T

Tob belongs to the anti-proliferative Tob/BTG family. The level of Tob throughout the cell cycle is regulated by the SCF (Skp1/Cullin/F-box protein)(Skp2) ubiquitin ligase (E3) complex. Here, we show that Coronin7 (CRN7) is also involved in Tob degradation. We identified CRN7 as a Tob-interacting molecule. A sequence containing two of the six WD motifs in the middle of CRN7 was ...
