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.

Disulfide-cross-linked tau and MAP2 homodimers readily promote microtubule assembly.

Di Noto L, DeTure MA, Purich DL

The neuronal proteins Tau and MAP2 use homologous C-terminal MT-binding regions (MTBRs) to interact with microtubules, F-actin, and intermediate filaments. Although Tau-MTBR is the principal component of pronase-treated Alzheimer paired helical filaments, both Tau and MAP2 form filaments in vitro from disulfide-linked homodimers. That the critical thiol lies within a domain needed for MT binding raised the question: Does disulfide ... [more]
