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.

Grd19/Snx3p functions as a cargo-specific adapter for retromer-dependent endocytic recycling.

Strochlic TI, Setty TG, Sitaram A, Burd CG

Amajor function of the endocytic system is the sorting of cargo to various organelles. Endocytic sorting of the yeast reductive iron transporter, which is composed of the Fet3 and Ftr1 proteins, is regulated by available iron. When iron is provided to iron-starved cells, Fet3p-Ftr1p is targeted to the lysosome-like vacuole and degraded. In contrast, when iron is not available, Fet3p-Ftr1p ... [more]
