Abstract
(EN) A binding molecule such as an antibody or CAR having specificity to an epitope within extracellular domain 3 (ECD3) of a unique short 28 (US28) protein of human cytomegalovirus (HCMV), wherein ECD3 of the US28 protein comprises an amino acid sequence presented in the US28 protein at positions corresponding to positions 167 to 183 of the US28 protein encoded by HCMV as set forth in SEQ ID NO:5. Further disclosed is a peptide or polypeptide comprising, consisting essentially of, or consisting of, the sequence TKKNNQCMTDYDYLEVS (SEQ ID NO: 6), or comprising the sequence of an immunogenic fragment of SEQ ID NO: 6; or a peptide or polypeptide comprising, consisting essentially of, or consisting of, the sequence TKKDNQCMTDYDYLEVS (SEQ ID NO:7), or comprising the sequence of an immunogenic fragment of SEQ ID NO: 7; wherein said peptide or polypeptide is not the US28 protein. Further disclosed are methods of screening for binding molecules which have binding specificity to an epitope within ECD3 of a US28 protein of HCMV.
