PG - 33-8 LID - 10.3881/j.issn.1000-503X.2011.01.008 [doi] AB - OBJECTIVE: To investigate the structure and function of the N-terminal region (NTR) of death receptor 5 (DR5). METHODS: A series of deletions of the DR5 extracellular domain (DR5-ECD) proteins were expressed in E.coli. and purified by affinity chromatography. The binding ability of these deletant proteins to AD5-10, a mouse anti-human DR5 monoclonal antibody, was evaluated by immunoblotting and ELISA. RESULTS: Recombinant DR5-ECD proteins containing the NTR were recognized and bound by AD5-10, while the other deletant proteins without the NTR failed to interact with AD5-10. CONCLUSION: There is an AD5-10 targeting site in the NTR of DR5, which may play a role in developing novel immunotherapies for cancers.
