An anti-EGFR nanobody was labeled at the C-terminus with a lysosome-sorting NPGY (Asn-Pro-Gly-Tyr) motif via sortase-mediated ligation to enhance the engagement of the clathrin-mediated endocytosis. The synergistic effects of NPGY motif and nona-arginine peptide were found to induce robust internalization and lysosomal trafficking, which in turn improved anti-tumor activity of an antibody-drug conjugate.
