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.
Publication
Both extracellular immunoglobin-like domains of CD80 contain residues critical for binding T cell surface receptors CTLA-4 and CD28.
The B7-related molecules CD80 and CD86 are expressed on antigen-presenting cells, bind the homologous T cell receptors CD28 and CTLA-4, and trigger costimulatory signals important for optimal T cell activation. All four molecules are immunoglobulin superfamily members, each comprising an extracellular Ig variable-like (IgV) domain, with CD80 and CD86 containing an additional Ig constant-like (IgC) domain. Despite limited sequence identity, ... [more]
