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.

The nuclear protein p34SEI-1 regulates the kinase activity of cyclin-dependent kinase 4 in a concentration-dependent manner.

Li J, Melvin WS, Tsai MD, Muscarella P

Previous studies have shown that p34(SEI-1), also known as TRIP-Br1, is involved in cell cycle regulations by interacting with a number of important proteins including CDK4. However, the detailed mechanism and structural basis of the interaction remains to be determined. We report the use of in vitro studies to address these problems. First, it was shown that p34(SEI-1) binds to ... [more]
