Abstract
A ligand regulated protein-protein interaction system based on a lipocalin-fold molecule including: (a) a lipocalin-fold molecule; (b) a lipocalin-fold ligand with a low molecular weight of 1500 Da or below; and (c) a lipocalin-fold binding interaction partner, wherein the lipocalin-fold molecule can bind to the lipocalin-fold ligand; and wherein the lipocalin-fold molecule bound to the lipocalin-fold ligand binds to the lipocalin-fold binding interaction partner with an affinity which is at least 10-fold higher than the affinity of the lipocalin-fold molecule not bound to the lipocalin-fold ligand; and wherein the lipocalin-fold binding interaction partner is not a naturally occurring protein which has an affinity of <10 μM to any naturally occurring lipocalin-fold molecule in the presence of any lipocalin-fold ligand.
