ABSTRACT:
A method for selecting novel proteins such as growth hormone variants having altered binding properties for a growth hormone receptor molecule is provided. The method comprises fusing a gene encoding a hormone 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. Disposed are preferred phagemid expression vectors and selected human growth hormone variants.
