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.

Chaperoning checkpoint kinase 1 (Chk1), an Hsp90 client, with purified chaperones.
Checkpoint kinase 1 (Chk1), a serine/threonine kinase that regulates DNA damage checkpoints, is destabilized when heat shock protein 90 (Hsp90) is inhibited, suggesting that Chk1 is an Hsp90 client. In the present work we examined the interplay between Chk1 and Hsp90 in intact cells, identified a source of unchaperoned Chk1, and report the in vitro chaperoning of Chk1 in reticulocyte ... [more]

| HSP90AA1 CHEK1 | Affinity Capture-Luminescence Affinity Capture-Luminescence An interaction is inferred when a bait protein, tagged with luciferase, is enzymatically detected in immunoprecipitates of the prey protein as light emission. The prey protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag. | High | - | BioGRID | - | |
| HSP90AA1 CHEK1 | 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. | Low | - | BioGRID | 611582 |
