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.

Purification and characterization of a protein binding to the SP6 kappa promoter. A potential role for CArG-box binding factor-A in kappa transcription.

Bemark M, Olsson H, Heinegard D, Leanderson T

A protein interacting with an A-T-rich region that is a positive control element within the SP6 kappa promoter was purified and identified as CArG-box binding factor-A. The purified protein was shown to interact specifically with the coding strand of single-stranded DNA and, with lower affinity, with double-stranded DNA. A mutation that inhibited binding of the protein to the A-T-rich region ... [more]
