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.

PKM2 compensates for proteasome dysfunction by mediating the formation of the CHIP-HSP70-BAG3 complex and the aggregation of ubiquitinated proteins.
Protein aggregation and degradation via autophagy (aggrephagy) are major strategies adopted by cells to remove misfolded polypeptides when there is proteasome dysfunction. The functional protein complex consisting of heat shock protein 70 (Hsp70), cochaperone ubiquitin ligase carboxyl-terminal of Hsp70/Hsp90 interacting protein (CHIP), and co-chaperone Bcl-2-associated athanogene 3 (BAG3) has been associated with the activation of protein aggregation. However, data on ... [more]

| PKM STUB1 | Reconstituted Complex Reconstituted Complex 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. | Low | - | BioGRID | - |
