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.

Association of immunophilins with mammalian TRPC channels.

Sinkins WG, Goel M, Estacion M, Schilling WP

Drosophila photoreceptor channels TRP and TRPL are held in a large signalplex by the scaffolding protein, INAD. Immunophilin FKBP59, another member of the signalplex, binds to both INAD and TRPL. Mutation P702Q or P709Q in the highly conserved TRPL sequence (701)LPPPFNVLP(709), eliminates TRPL interaction with FKBP59. The first leucylprolyl (LP) dipeptide in this region is conserved in mammalian TRPC channel ... [more]
