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.

miRNA-mediated deadenylation is orchestrated by GW182 through two conserved motifs that interact with CCR4-NOT.

miRNAs recruit the miRNA-induced silencing complex (miRISC), which includes Argonaute and GW182 as core proteins. GW182 proteins effect translational repression and deadenylation of target mRNAs. However, the molecular mechanisms of GW182-mediated repression remain obscure. We show here that human GW182 independently interacts with the PAN2-PAN3 and CCR4-NOT deadenylase complexes. Interaction of GW182 with CCR4-NOT is mediated by two newly discovered ... [more]
