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.

Complement C4bC2 complex formation: an investigation by surface plasmon resonance.

Laich A, Sim RB

Complex formation between the human complement proteins C4b and C2 was investigated by surface plasmon resonance. C4b was immobilised and C2 was used in the fluid phase to measure interaction at different ionic strengths (30-830 mM NaCl) and in the absence and presence of MgCl2. Maximum binding was observed at 30 mM NaCl, and was negligible above 300 mM NaCl. ... [more]
