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.

Identification of an overlapping binding domain on Cdc20 for Mad2 and anaphase-promoting complex: model for spindle checkpoint regulation.

Zhang Y, Lees E

Activation of the anaphase-promoting complex (APC) is required for anaphase initiation and for exit from mitosis in mammalian cells. Cdc20, which specifically recognizes APC substrates involved in the metaphase-to-anaphase transition, plays a pivotal role in APC activation through direct interaction with the APC. The activation of the APC by Cdc20 is prevented by the interaction of Cdc20 with Mad2 when ... [more]
