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.

Ubiquitin-specific protease 2b negatively regulates IFN-β production and antiviral activity by targeting TANK-binding kinase 1.

Zhang L, Zhao X, Zhang M, Zhao W, Gao C

TANK-binding kinase 1 (TBK1) is essential for IFN regulatory factor 3 activation and IFN-β production downstream of various innate receptors. However, how TBK1 activation is terminated is not well defined. In this study, we identified ubiquitin-specific protease (USP) 2b as a new negative regulator for TBK1 activation. Overexpression of USP2b inhibited retinoic acid-inducible gene-I-mediated IFN-β signaling; in contrast, knockdown of ... [more]
