description On décrit une méthode de sélection de nouvelles protéines telle que des variantes de l'hormone de croissance et de fragments d'anticorps possédant des propriétés de liaison modifiées envers leurs molécules réceptrices correspondantes. La méthode comprend la fusion d'un gène codant une protéine intéressante avec le domaine terminal carboxy de la protéine enveloppe du gène III du phage M13 filamenteux. La fusion de gènes est mutée de façon à constituer une bibliothèque de protéines de fusion structuralement apparentées dont l'expression se fait en faible quantité sur la surface d'une particule phagémide. On emploie la sélection biologique ainsi que le criblage pour l'identification de nouveaux ligands efficaces comme médicaments potentiels. On décrit des vecteurs d'expression phagémide préférés et des variantes de l'hormone de croissance humaine sélectionnées. A method for selecting novel proteins such as growth hormone and antibody fragment variants having altered binding properties for their respective receptor molecules is provided. The method comprises fusing a gene encoding a protein of interest to the carboxy terminal domain of the gene III coat protein of the filamentous phage M13. The gene fusion is mutated to form a library of structurally related fusion proteins that are expressed in low quantity on the surface of a phagemid particle. Biological selection and screening are employed to identify novel ligands useful as drug candidates. Disclosed are preferred phagemid expression vectors and selected human growth hormone variants.
