Disclosed is a ligand regulated protein-protein interaction system based on a lipocalin-fold molecule comprising:
(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.
The invention provides natural allosteric modulators that are useful as sweet flavor enhancers. The present invention also includes ingestible compositions comprising the present compounds and methods of enhancing the sweet taste of sweeteners and sugars.

Disclosed is a group of chimeric antigen receptors (CARs) consisting of two, three or four CAR molecules, wherein each member of the group of CARs is different in its amino acid sequence from one another, and wherein each of the CAR molecules of the group comprise at least a transmembrane domain and an ectodomain, wherein the ectodomain comprises one or two antigen binding moieties and/or one or two binding sites to which other polypeptides each comprising at least an antigen binding moiety are able to bind; wherein the ectodomain of each CAR molecule of the group in its prevalent conformation is free of cysteine amino acid moieties which are able to form intermolecular disulphide bonds with other CAR molecules of the group, respectively, and wherein each CAR molecule of the group comprises at least one heterodimerization domain.

Disclosed is agroup of chimeric antigen receptors (CARs) consisting of two, three or four CAR molecules, wherein the members of the group of CARs can be different or identical in their amino acid sequences to one another, and wherein each of the CAR molecules of the group comprise at least a transmembrane domain and an ectodomain comprising either an antigen binding moiety or a binding site to which another polypeptide is able to bind, wherein the another polypeptide comprises an antigen binding moiety; wherein each CAR molecule of the group comprises at least one dimerization domain, wherein this dimerization of a pair of dimerization domains is either induced by a regulating molecule and optionally reduced by another regulating molecule, or occurs in the absence of a regulating molecule and is reduced by a regulating molecule, and wherein the ectodomain of each CAR molecule of the group in its prevalent conformation is free of cysteine amino acid moieties which are able to form intermolecular disulphide bonds with other CAR molecules of the group, respectively, and wherein the antigen binding moieties of the CAR molecules of the group and of the other polypeptides being able to bind to the CAR molecules of the group are either specific for one target antigen or for a non-covalent or a covalent complex of different target antigens.
