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.

Tyrosine phosphorylation of plakoglobin causes contrary effects on its association with desmosomes and adherens junction components and modulates beta-catenin-mediated transcription.

Miravet S, Piedra J, Castano J, Raurell I, Franci C, Dunach M, Garcia de Herreros A

Plakoglobin is a protein closely related to beta-catenin that links desmosomal cadherins to intermediate filaments. Plakoglobin can also substitute for beta-catenin in adherens junctions, providing a connection between E-cadherin and alpha-catenin. Association of beta-catenin with E-cadherin and alpha-catenin is regulated by phosphorylation of specific tyrosine residues; modification of beta-catenin Tyr654 and Tyr142 decreases binding to E-cadherin and alpha-catenin, respectively.

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.
