CC49-ζ vector diagram. A gamma retroviral CAR construct consisting of a TAG-72 antigen-binding domain derived from the humanized CC49 single-chain antibody linked to the CD3-ζ signaling domain of the T-cell receptor via a human CD4 transmembrane domain. CAR, chimeric antigen receptor; Fv, variable fragment; (G4-S)3, (Gly4, Ser)3 peptide linker; IC, intracellular; TM, transmembrane; VH, variable heavy chain; VL, variable light chain; γ1, immunoglobulin γ1
