Here we report a cryo-electron microscopy structure of human TCRαβ in complex with the CD3 hexamer at 3.7 Å resolution. The structure contains the complete extracellular domains and all the transmembrane helices of TCR-CD3.
6JXR: Structure of human T cell receptor-CD3 complex - RCSB PDB
Here we report a cryo-electron microscopy structure of human TCRαβ in complex with the CD3 hexamer at 3.7 Å resolution. The structure contains the complete extracellular domains and all the transmembrane helices of TCR-CD3.
Structural Biology of the T-cell Receptor: Insights into Receptor ...
The T-cell receptor (TCR)-CD3 complex serves as a central paradigm for general principles of receptor assembly, ligand recognition, and signaling in the immune system. There is no other receptor system that matches the diversity of both receptor and ...
Given the central role of the human CD3 heterodimer in the immune response and the therapeutic value of OKT3, we have elucidated the crystal structure of this complex to 2.1-Å resolution. Cloning, Expression, and Purification of CD3 and OKT3 Complex Formation.
The Full Model of the pMHC-TCR-CD3 Complex: A Structural and …
TCR:CD3 complex structure. The CD3 chains interact with the terminal region of the TCR (magenta and green) through non-covalent bonds. Each chain is magnified in the box. The ITAM region, containing the tyrosine residues, is indicated in the CD3δ chain box as reference.
Molecular mechanisms for the assembly of the T cell receptor–CD3 ...
The T cell receptor (TCR)–CD3 complex represents on of the most intricate membrane receptor structures since it is built from six distinct chains. This complexity led to a number of different proposals for the arrangement of the receptor subunits, ...
Structural understanding of T cell receptor triggering
2020年2月11日 · TCR is an intricate protein complex comprising a disulfide-linked TCRαβ heterodimer noncovalently associated with CD3 signaling subunits, namely, CD3ζζ, CD3δε, and CD3γε (reviewed by Jennifer E....
Structures of human γδ T cell receptor–CD3 complex
2024年4月24日 · Here we present two cryo-electron microscopy (cryo-EM) structures of unliganded human Vγ9Vδ2 and Vγ5Vδ1 TCR–CD3 complexes, revealing two distinct assembly mechanisms that depend on specific Vγ subset use.
