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.

Stress granules regulate double-stranded RNA-dependent protein kinase activation through a complex containing G3BP1 and Caprin1.

Reineke LC, Kedersha N, Langereis MA, van Kuppeveld FJ, Lloyd RE

Stress granules (SGs) are dynamic cytoplasmic repositories containing translationally silenced mRNAs that assemble upon cellular stress. We recently reported that the SG nucleating protein G3BP1 promotes antiviral activity and is essential in double-stranded RNA-dependent protein kinase (PKR) recruitment to stress granules, thereby driving phosphorylation of the ? subunit of eukaryotic initiation factor 2 (eIF2?). Here, we delineate the mechanism for ... [more]

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.
