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.

KCNE2 confers background current characteristics to the cardiac KCNQ1 potassium channel.
Mutations in HERG and KCNQ1 (or KVLQT1) genes cause the life-threatening Long QT syndrome. These genes encode K(+) channel pore-forming subunits that associate with ancillary subunits from the KCNE family to underlie the two components, I(Kr) and I(Ks), of the human cardiac delayed rectifier current I(K). The KCNE family comprises at least three members. KCNE1 (IsK or MinK) recapitulates I(Ks) ... [more]
