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.

Integral membrane proteins of the nuclear envelope interact with lamins and chromosomes, and binding is modulated by mitotic phosphorylation.

Foisner R, Gerace L

Lamina-associated polypeptides (LAPs) 1A, 1B, 1C, and 2 are integral membrane proteins of the nuclear envelope associated with the nuclear lamina. Using in vitro assays, we show that LAPs 1A and 1B specifically bind to both lamins A and C and lamin B1, while LAP 2 associates only with lamin B1. LAP 2 also binds to mitotic chromosomes. The LAPs ... [more]
