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.

Ataxin-2 associates with the endocytosis complex and affects EGF receptor trafficking.

Nonis D, Schmidt MH, van de Loo S, Eich F, Dikic I, Nowock J, Auburger G

Ataxin-2 is a novel protein, where the unstable expansion of an internal polyglutamine domain can cause the neurodegenerative disease Spinocerebellar Ataxia type 2 (SCA2). To elucidate its cellular function, we have used full-length ataxin-2 as bait in a yeast two-hybrid screen of human adult brain cDNA. As binding partners we found endophilin A1 and A3, two brain-expressed members of the ... [more]
