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.

Pak1 kinase homodimers are autoinhibited in trans and dissociated upon activation by Cdc42 and Rac1.
Pak1, a serine/threonine kinase that regulates the actin cytoskeleton, is an effector of the Rho family GTPases Cdc42 and Rac1. The crystal structure of Pak1 revealed an autoinhibited dimer that must dissociate upon GTPase binding. We show that Pak1 forms homodimers in vivo and that its dimerization is regulated by the intracellular level of GTP-Cdc42 or GTP-Rac1. The dimerized Pak1 ... [more]
