MART-1(27-35) EPITOPE-SPECIFIC T CELL RECEPTOR

摘要

Provided is a MART-1(27-35) epitope-specific T cell receptor, comprising an α chain and a β chain. The α chain comprises three complementary determining regions, respective sequences thereof being positions 61-66, positions 84-89, and positions 124-136 of SEQ ID No.3. The β chain comprises three complementary determining regions, respective amino acid sequences thereof being positions 46-50, positions 68-73 and positions 112-125 of SEQ ID No.4. A T cell expressing the TCR can effectively recognize a MART-1(27-35) epitope polypeptide supported on a T2 cell and secrete IFN-γ, thereby demonstrating the functionality of the receptor. Use of the TCR with a relevant drug target allows for effective drug development.
