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.

Role of 14-3-3gamma in FE65-dependent gene transactivation mediated by the amyloid beta-protein precursor cytoplasmic fragment.

Sumioka A, Nagaishi S, Yoshida T, Lin A, Miura M, Suzuki T

The amyloid beta-protein precursor intracellular domain fragment (AICD) is generated from amyloid beta-protein precursor by consecutive cleavages. AICD is thought to activate FE65-dependent gene expression, but the molecular mechanism remains under consideration. We found that dimeric 14-3-3gamma bound both AICD and FE65 simultaneously, and this binding facilitated FE65-dependent gene transactivation by enhancing the association of AICD with FE65. 14-3-3gamma bound ...
