Affinity Capture-MS

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 is identified by mass spectrometric methods.

E3 ligases partner with E2 enzymes to regulate vast eukaryotic biology. The hierarchical nature of these pairings, with >600 E3s and ~40 E2s in humans, necessitates that E2s cofunction with numerous different E3s. Here, focusing on E3s in the RING-between-RING (RBR) family and their partner UBE2L3 and UBE2D-family E2s, we report an approach to interrogate selected pathways. We screened phage-displayed ...

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.
