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.

Celastrol recruits UBE3A to recognize and degrade the DNA binding domain of steroid receptors.

Strategies to degrade steroid receptors and their alternative splicing isoforms are critical for disease management. Here we report that celastrol recruited the ubiquitin ligase UBE3A and degraded androgen receptor (AR), AR-v7, and glucocorticoid receptor (GR) to suppress prostate cancer development. UBE3A was not an optimal endogenous AR ubiquitin ligase in mice and patients, but celastrol promoted the interaction between UBE3A ... [more]
