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.

An interaction between the DNA repair factor XPA and replication protein A appears essential for nucleotide excision repair.

Li L, Lu X, Peterson CA, Legerski RJ

Replication protein A (RPA) is required for simian virus 40-directed DNA replication in vitro and for nucleotide excision repair (NER). Here we report that RPA and the human repair protein XPA specifically interact both in vitro and in vivo. Mapping of the RPA-interactive domains in XPA revealed that both of the largest subunits of RPA, RPA-70 and RPA-34, interact with ... [more]
