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 Hedgehog-inducible ubiquitin ligase subunit WSB-1 modulates thyroid hormone activation and PTHrP secretion in the developing growth plate.

WSB-1 is a SOCS-box-containing WD-40 protein of unknown function that is induced by Hedgehog signalling in embryonic structures during chicken development. Here we show that WSB-1 is part of an E3 ubiquitin ligase for the thyroid-hormone-activating type 2 iodothyronine deiodinase (D2). The WD-40 propeller of WSB-1 recognizes an 18-amino-acid loop in D2 that confers metabolic instability, whereas the SOCS-box domain ... [more]
