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.

De novo DNA methyltransferase DNMT3b interacts with NEDD8-modified proteins.

Shamay M, Greenway M, Liao G, Ambinder RF, Hayward SD

DNA methylation and histone modifications play an important role in transcription regulation. In cancer cells, many promoters become aberrantly methylated through the activity of the de novo DNA methyltransferases DNMT3a and DNMT3b and acquire repressive chromatin marks. NEDD8 is a ubiquitin-like protein modifier that is conjugated to target proteins, such as cullins, to regulate their activity, and cullin 4A (CUL4A) ... [more]
