The present disclosure provides compositions and methods for high throughput Gain of Function (GOF) sorting to discover and develop novel and highly selective candidate drug molecules. High throughput GOF sorting includes: mutating a single residue in a receptor and/or ligand; measuring the affinity and functional activity of the resulting ligand target-ligand interaction; and carrying out multiple rounds of mutation and measurement to determine which residues provide key interaction points underlying the functional activity of a ligand target-ligand interaction. Further, the present disclosure provides methods and compositions for high throughput and high precision GOF sorting, such that large numbers of mutations can be generated and screened rapidly, and GOF compounds can be identified and isolated.

La présente invention concerne des compositions et des procédés de tri de gain de fonction (GOF) à grande capacité permettant de découvrir et de développer de nouvelles molécules de médicaments candidats hautement sélectives. Ce tri de gain de fonction à grande capacité consiste : à effectuer la mutation d'un seul résidu dans un récepteur et/ou un ligand ; à mesurer l'affinité et l'activité fonctionnelle de l'interaction ligand cible-ligand obtenue ; et à mettre en oeuvre de multiples cycles de mutation et de mesure afin qu'on puisse déterminer quels sont les résidus qui constituent des points d'interaction clés à la base de l'activité fonctionnelle d'une interaction ligand cible-ligand. La présente invention concerne par ailleurs des procédés et des compositions permettant d'obtenir un tri de gain de fonction à grande capacité et de haute précision permettant de générer et d'analyser rapidement de grands nombres de mutations et d'identifier puis d'isoler des composés à gain de fonction.
