Abstract
The present disclosure provides dimeric antigen receptors (DAR) constructs comprising a heavy chain binding region on one polypeptide chain and a light chain binding region on a separate polypeptide chain. The two polypeptide chains that make up the dimeric antigen receptors can dimerize to form an antigen binding domain. The dimeric antigen receptors have antibody-like properties as they bind specifically to a target antigen. The dimeric antigen receptors can be used for directed cell therapy.
Claims10
A nucleic acid encoding a precursor polypeptide comprising ten regions ordered from the amino terminus to the carboxyl terminus:
- (1) a heavy chain leader sequence, (2) an antibody heavy chain variable region comprising a CD38 antibody heavy chain variable region which comprises the amino acid sequence of SEQ ID NO:1, (3) an antibody heavy chain constant region, (4) an optional hinge region, (5) a transmembrane region, (6) an intracellular signaling region, (7) a T2A cleavage sequence, (8) a light chain leader sequence, (9) an antibody light chain variable region comprising a CD38 antibody light chain variable region which comprises the amino acid sequence of SEQ ID NO:3, and (10) an antibody light chain constant region.
