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.

Paip1, an effective stimulator of translation initation, is targeted by WWP2 for ubiquitination and degradation.

Lv Y, Zhang K, Gao H

Poly(A)-binding protein-interacting protein 1 (Paip1) stimulates translational initiation by inducing the circularization of mRNA. However, the mechanisms underlying Paip1 regulation, particularly its protein stability, are still unclear. Here we show that the E6AP carboxyl terminus (HECT)-type ubiquitin ligase WW domain-containing protein 2 (WWP2), a homolog of HECT-type ubiquitin ligase WWP1, interacts with and targets Paip1 for ubiquitination and proteasomal degradation. ...
