BINDING POLYPEPTIDES HAVING A MUTATED SCAFFOLD

摘要

The present disclosure relates to a class of engineered polypeptides and provides a polypeptide comprising the sequence EX2X3X4AX6X7EIX10 X11 LPNLX16X17X18QX20 X21AFIX25X26LX28X29X30 PX32QSX35X36LLX39E AKKX45X46X47Q. The present disclosure also relates to populations of polypeptide variants based on a common scaffold, each polypeptide in the population comprising the amino acid sequence EX2X3X4AX6X7EIX10 X11 LPNLX16X17X18QX20 X21AFIX25X26LX28X29X30 PX32QSX35X36LLX39E AKKLX45X46X47Q, and methods for selecting a desired polypeptide having an affinity for a predetermined target from said population.
