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.

TREM2 Binds to Apolipoproteins, Including APOE and CLU/APOJ, and Thereby Facilitates Uptake of Amyloid-Beta by Microglia.
Genetic variants of TREM2, a protein expressed selectively by microglia in the brain, are associated with Alzheimer's disease (AD). Starting from an unbiased protein microarray screen, we identified a set of lipoprotein particles (including LDL) and apolipoproteins (including CLU/APOJ and APOE) as ligands of TREM2. Binding of these ligands by TREM2 was abolished or reduced by disease-associated mutations. Overexpression of wild-type ... [more]
Throughput
- Low Throughput
Additional Notes
- assayed using BLI (biolayer interferometry); some interactions required prior lipidation of the hit protein
