ANTIGENIC DETERMINANTS RECOGNIZED BY ANTI-HUMAN DEATH RECEPTOR DR5 MONOCLONAL ANTIBODY AD5-10, DERIVATIVES AND USES THEREOF

摘要

Provided are antigenic determinants recognized by anti-human death receptor DR5 monoclonal antibody AD5-10, derivatives and uses thereof. The antigenic determinants have the amino acid sequence of LITQQDLAPAARA, wherein the core polypeptide is QDLAP. The polypeptides comprising said antigenic determinants can activate the signal pathway downstream of DR5 after binding to monoclonal antibody AD5-10, then result in apoptosis. The antigenic determinants and derivatives thereof can be used for screening and preparing anti-human DR5 agonistic antibody, small molecular compound binding to DR5 and DR5 vaccine. Their nucleotide encoding sequences can be used for preparing antisense nucleotides and small molecular ribonucleotides for treating and preventing tumor and/or AIDS and the like.
