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.

Rim, a component of the presynaptic active zone and modulator of exocytosis, binds 14-3-3 through its N terminus.

Sun L, Bittner MA, Holz RW

Rim1, a brain-specific Rab3a-binding protein, localizes to the presynaptic cytomatrix and plays an important role in synaptic transmission and synaptic plasticity. Rim2, a homologous protein, is more ubiquitously expressed and is found in neuroendocrine cells as well as in brain. Both Rim1 and Rim2 contain multiple domains, including an N-terminal zinc finger, which in Rim1 strongly enhances secretion in chromaffin ... [more]
