Structural basis of assembly of the human T cell receptor–CD3 …
网页2019年8月28日 · A high-resolution cryo-electron microscopy structure of the human octameric T cell receptor–CD3 complex, including the complete extracellular and transmembrane domains, reveals the structural...
Structure-based engineering of a novel CD3ε-targeting antibody …
网页2023年3月29日 · Using insights from the crystal structure of anti-Hu/Cy CD3 antibody ADI-26906 in complex with CD3ε and antibody engineering using a yeast-based platform, we have derived high-affinity CD3 antibody variants with very low polyreactivity and significantly improved biophysical developability.
A conformational epitope expressed upon association of CD3 …
网页1991年11月1日 · However, these antibodies very strongly stained COS cells doubly transfected with a combination of CD3-epsilon plus either CD3-gamma or CD3-delta. By contrast, the antibodies SP34 and APA 1/1, which were raised against isolated SDS-denatured CD3-epsilon protein, gave a strong staining of COS cells singly transfected with CD3-epsilon as well as ...
Crystal structure of a human CD3-epsilon/delta dimer in ... - PubMed
网页2004年11月16日 · We report the crystal structure at 1.9-A resolution of a complex between a human CD3-epsilon/delta ectodomain heterodimer and a single-chain fragment of the UCHT1 antibody. CD3-epsilon/delta and CD3-epsilon/gamma share a conserved interface between the Ig-fold ectodomains, with parallel packing of the two G strands.
RCSB PDB - 1XIW: Crystal structure of human CD3-e/d dimer in …
网页2004年9月22日 · We report the crystal structure at 1.9-A resolution of a complex between a human CD3-epsilon/delta ectodomain heterodimer and a single-chain fragment of the UCHT1 antibody. CD3-epsilon/delta and CD3-epsilon/gamma share a conserved interface between the Ig-fold ectodomains, with parallel packing of the two G strands.
Expression and characterization of recombinant soluble monkey CD3 ...
网页2004年3月1日 · SP34 monoclonal antibody had been generated by immunization with human CD3-ε chain (Wileman et al., 1990) and is reactive with monkey T cells. The question then arose as to the epitope specificity of FN18 in regard to the CD3 chains, as well as the CD3 structure of the SP34 + FN18 − T cells observed …
A Novel Her2/VEGFR2/CD3 trispecific antibody with an optimal …
网页2022年11月14日 · To fulfill the optimal geometry between target cells and T cells, three formats of Her2/CD3 or VEGFR2/CD3 bsAbs were designed by site-specifically fusing a Her2-specific nanobody (2Rs15d) or VEGFR2-targeted nanobody (3VGR19) to the defined sites of the HC or LC of CD3-targeted antibody Fab (SP34): Her2/CD3 HNT (2Rs15d fused to the N-terminus of ...
Crystal structure of a human CD3-ε/δ dimer in complex with a …
网页2004年11月11日 · We have determined the crystal structure of a human CD3-ε/δ extracellular domain dimer complexed with a variable-domain fragment of the antibody UCHT1. This structure completes the catalog of TCR/CD3 ectodomains and constrains possible models for the complete assembly.
