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.

Arkadia complexes with clathrin adaptor AP2 and regulates EGF signalling.

Mizutani A, Saitoh M, Imamura T, Miyazawa K, Miyazono K

Arkadia is a positive regulator of transforming growth factor (TGF)-β signalling that induces ubiquitin-dependent degradation of several inhibitory proteins of TGF-β signalling through its C-terminal RING domain. We report here that, through yeast-two-hybrid screening for Arkadia-binding proteins, the µ2 subunit of clathrin-adaptor 2 (AP2) complex was identified as an interacting partner of Arkadia. Arkadia was located in both the nucleus ... [more]
