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.

A post-ubiquitination role for MDM2 and hHR23A in the p53 degradation pathway.

Brignone C, Bradley KE, Kisselev AF, Grossman SR

Abrogation of ubiquitin/proteasome-dependent turnover of p53 is critical for its activation. UbL-UBA proteins, including human homolog of Rad23 (hHR23) proteins, may regulate proteasomal degradation of substrates such as p53, due to their ability to interact with both ubiquitinated substrates and the proteasome. siRNA-mediated depletion of hHR23A or hHR23B in human cell lines accelerated p53 degradation. In contrast, overexpression of hHR23 ... [more]

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.
