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.

A central role of Cwc25 in spliceosome dynamics during the catalytic phase of pre-mRNA splicing.

Tseng CK, Chung CS, Chen HC, Cheng SC

Splicing of precursor mRNA occurs via two consecutive steps of transesterification reaction; both require ATP and several proteins. Despite the energy requirement in the catalytic phase, incubation of the purified spliceosome under proper ionic conditions can elicit competitive reversible transesterification, debranching, and spliced-exon-reopening reactions without the necessity for ATP or other factors, suggesting that small changes in the conformational state ...
