FIELD: medicine. n SUBSTANCE: there are described versions of polypeptides specifically binding human DR5 each of which contains CDR versions containing a high-limited variety of amino acid sequences. There are described versions of polypeptides fused with at least a portion of protein, viral envelopes specifically binding human DR5. There are offered: a coding nucleic acid, an expression vector, as well as a cell for polypeptide expression containing the vector. What is also described is a method for producing the polypeptide by cell culture and a method for selecting an antigen-binding variable domain using the polypeptide. Besides, there are presented compositions and methods for using for the purpose of treating a malignant tumour and conditions related to the immune system. n EFFECT: use of the invention can find application in medicine in treating and diagnosing the tumour diseases. n 88 cl, 29 dwg, 1 tbl, 6 ex |
