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 SCF-Fbxo40 complex induces IRS1 ubiquitination in skeletal muscle, limiting IGF1 signaling.
Insulin-like growth factor 1 (IGF1) induces skeletal muscle hypertrophy by activating the IGF1R/IRS1/PI3K/Akt pathway. However the effect of IGF1 in differentiated muscle is limited by IRS1 ubiquitination and proteasome-mediated breakdown. In skeletal muscle, IGF1R activation sensitizes IRS1 to degradation, and a screen for the responsible E3 ligase identified Fbxo40 as mediating this rapid turnover of IRS1, since IRS1 loss can ...
