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.

Transcriptional Suppression by Transient Recruitment of ARIP4 to Sumoylated nuclear receptor Ad4BP/SF-1.

Ogawa H, Komatsu T, Hiraoka Y, Morohashi K

The small ubiquitin-like modifier SUMO conjugates transcription factors and suppresses their respective activation of target genes. Although various SUMO-modified transcription factors have been isolated, mechanisms whereby sumoylated-substrates modulate transcription remain unknown. Here, we purified ARIP4 (AR interacting protein 4, a Rad54 family member and a SNF2 chromatin remodeling factor), which interacts with sumoylated Ad4BP/SF-1 through two SUMO-interacting motifs and one ...
