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 ...

Co-crystal Structure

Interaction directly demonstrated at the atomic level by X-ray crystallography. Also used for NMR or Electron Microscopy (EM) structures. If there is no obvious bait-hit directionality to the interaction involving 3 or more proteins, then the co-crystallized proteins should be listed as a complex.

An interaction is inferred when close proximity of interaction partners is detected by fluorescence resonance energy transfer between pairs of fluorophore-labeled molecules, such as occurs between CFP (donor) and YFP (acceptor) fusion proteins.
