Novel polypeptide selective binding with human programmed cell death protein 1 protein and uses thereof

摘要

The present invention is a novel polypeptide capable of specifically binding to the programmed apoptosis protein 1, a polynucleotide encoding the polypeptide, a vector containing the polynucleotide, a recombinant microorganism into which the expression vector was introduced, and using the recombinant microorganism. It relates to a method for preventing or treating cancer, comprising administering a method for preparing the polypeptide, a composition for preventing or treating cancer comprising the polypeptide, and a composition for preventing or treating cancer comprising the polypeptide. Since the polypeptide of the present invention can bind to programmed apoptosis protein 1 and inhibit its activity, it can be widely used as a preparation for preventing or treating various diseases associated with programmed apoptosis protein 1.
