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.

The plexin-B1/Rac interaction inhibits PAK activation and enhances Sema4D ligand binding.
The small GTPase Rac has been implicated in growth cone guidance mediated by semaphorins and their receptors. Here we demonstrate that plexin-B1, a receptor for Semaphorin4D (Sema4D), and p21-activated kinase (PAK) can compete for the interaction with active Rac and plexin-B1 can inhibit Rac-induced PAK activation. We have also demonstrated that expression of active Rac enhances the ability of plexin-B1 ... [more]
