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.

Proteomics analysis of Ring1B/Rnf2 interactors identifies a novel complex with the Fbxl10/Jhdm1B histone demethylase and the Bcl6 interacting corepressor.

Sanchez C, Sanchez I, Demmers JA, Rodriguez P, Strouboulis J, Vidal M

Ring1B/Rnf2 is a RING finger protein member of the Polycomb group (PcG) of proteins, which form chromatin-modifying complexes essential for embryonic development and stem cell renewal and which are commonly deregulated in cancer. Ring1B/Rnf2 is a ubiquitin E3 ligase that catalyzes the monoubiquitylation of the histone H2A, one of the histone modifications needed for the transcriptional repression activity of the ... [more]
