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.

CD40-tumor necrosis factor receptor-associated factor (TRAF) interactions: regulation of CD40 signaling through multiple TRAF binding sites and TRAF hetero-oligomerization.

Pullen SS, Miller HG, Everdeen DS, Dang TT, Crute JJ, Kehry MR

CD40 is a TNF receptor superfamily member that provides activation signals in antigen-presenting cells such as B cells, macrophages, and dendritic cells. Multimerization of CD40 by its ligand initiates signaling by recruiting TNF receptor-associated factors (TRAFs) to the CD40 cytoplasmic domain. Recombinant human TRAF proteins overexpressed in insect cells were biochemically characterized and used to finely map TRAF binding regions ... [more]

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.

FRET

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.
