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.

Pin1 regulates turnover and subcellular localization of beta-catenin by inhibiting its interaction with APC.

Ryo A, Nakamura M, Wulf G, Liou YC, Lu KP

Phosphorylation on a serine or threonine residue preceding proline (Ser/Thr-Pro) is a key regulatory mechanism, and the conformation of certain phosphorylated Ser/Thr-Pro bonds is regulated specifically by the prolyl isomerase Pin1. Whereas the inhibition of Pin1 induces apoptosis, Pin1 is strikingly overexpressed in a subset of human tumours. Here we show that Pin1 regulates beta-catenin turnover and subcellular localization by ... [more]

Throughput

  • Low Throughput

Additional Notes

  • Pin1 directly binds a phosphorylated Ser-Pro motif next to the APC-binding site in beta-catenin, inhibits its interaction with APC and increases its translocation into the nucleus
