NCIt definition : A bivalent recombinant fusion protein immunotoxin derived from the anti-CD3 monoclonal
antibody UCHT1 with potential antineoplastic activity. Anti-CD3 immunotoxin A-dmDT390-bisFv(UCHT1)
consists of 1-390 amino acid residues of chain A diphtheria toxin (DT) joined via
a spacer to the Fv fragment of UCHT1, which is connected to a second UCHT1 Fv fragment
via a disulfide bond (hence the bisFv designation); the addition of the second Fv
fragment overcomes the steric hindrance of immunotoxin binding due to the large N-terminal
DT domain. Once inside target T cells, the DT moiety catalyzes the transfer of the
ADP-ribose moiety of NAD to diphthamide, a posttranslationally modified histidine
residue found in elongation factor 2 (EF-2); inactivation of EF-2, disruption of polypeptide
chain elongation, and cell death ensue. CD3 is a complex of five cell-surface polypeptides
associated with the T cell receptor (TCR) complex.;
