An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.

Chibby, a nuclear beta-catenin-associated antagonist of the Wnt/Wingless pathway.

Takemaru K, Yamaguchi S, Lee YS, Zhang Y, Carthew RW, Moon RT

Inappropriate activation of downstream target genes by the oncoprotein beta-catenin is implicated in development of numerous human cancers. beta-catenin and its fruitfly counterpart Armadillo act as a coactivator in the canonical Wnt/Wingless pathway by binding to Tcf/Lef transcription factors. Here we report a conserved nuclear protein, named Chibby, which was identified in a screen for proteins that directly interact with ... [more]

CBY1 CTNNB1	Affinity Capture-Western 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.
