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.

Munc 18a binding to syntaxin 1A and 1B isoforms defines its localization at the plasma membrane and blocks SNARE assembly in a three-hybrid system assay.
Syntaxin 1 and synaptobrevin/VAMP play an essential role in synaptic vesicle exocytosis. Two isoforms for each of these proteins, syntaxins 1A and 1B and synaptobrevin/VAMPs 1 and 2, have been found in nerve endings. Morphological and biochemical studies have revealed a characteristic colocalization and selective interactions patterns of syntaxin 1 and synaptobrevin/VAMP isoforms in nervous and endocrine systems. Moreover, studies ... [more]
