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.

Insertions within the actin core of Actin-related protein 3 (Arp3) modulate branching nucleation by Arp2/3 complex.

Liu SL, May JR, Helgeson LA, Nolen BJ

The Arp2/3 (Actin-related protein 2/3) complex nucleates branched actin filaments involved in multiple cellular functions, including endocytosis and cellular motility. Two subunits (Arp2 and Arp3) in this seven-subunit assembly are closely related to actin, and upon activation of the complex form a ″cryptic dimer″ that stably mimics an actin dimer to nucleate a new filament. Both Arps contain a shared ... [more]

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.
