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.

Breast cancer metastasis suppressor 1 (BRMS1) is destabilized by the Cul3-SPOP E3 ubiquitin ligase complex.

Breast cancer metastasis suppressor 1 (BRMS1) suppresses metastasis without affecting primary tumorigenesis. The regulatory mechanism of BRMS1 at the protein level has not been revealed until recently. Here, we found that cullin 3 (Cul3), a component of E3 ubiquitin ligase, is a new binding partner of BRMS1 and the interaction between BRMS1 and Cul3 is mediated by the SPOP adaptor ... [more]
