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.

Three human RNA polymerase III-specific subunits form a subcomplex with a selective function in specific transcription initiation.

Wang Z, Roeder RG

Transcription by RNA polymerase III involves recruitment of the polymerase by template-bound accessory factors, followed by initiation, elongation, and termination steps. An immunopurification approach has been used to demonstrate that human RNA Pol III is composed of 16 subunits, some of which are apparently modified in HeLa cells. Partial denaturing conditions and sucrose gradient sedimentation at high salt result in ... [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.
