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.

Architecture of the RNA polymerase II preinitiation complex and mechanism of ATP-dependent promoter opening.

Gruenberg S, Warfield L, Hahn S

Yeast RNA polymerase II (Pol II) general transcription factor TFIIE and the TFIIH subunit Ssl2 (yeast ortholog of mammalian XPB) function in the transition of the preinitiation complex (PIC) to the open complex. We show that the three TFIIE winged-helix (WH) domains form a heterodimer, with the Tfa1 (TFIIEα) WH binding the Pol II clamp and the Tfa2 (TFIIEβ) tandem ... [more]

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
