Citation | Journal: bioRxiv / Year: 2024Title: The resting and ligand-bound states of the membrane-embedded human T-cell receptor-CD3 complex. Authors: Ryan Q Notti / Fei Yi / Søren Heissel / Martin W Bush / Zaki Molvi / Pujita Das / Henrik Molina / Christopher A Klebanoff / Thomas Walz Abstract: The T-cell receptor (TCR) initiates T-lymphocyte activation, but mechanistic questions remain( ). Here, we present cryogenic electron microscopy structures for the unliganded and human leukocyte ...The T-cell receptor (TCR) initiates T-lymphocyte activation, but mechanistic questions remain( ). Here, we present cryogenic electron microscopy structures for the unliganded and human leukocyte antigen (HLA)-bound human TCR-CD3 complex in nanodiscs that provide a native-like lipid environment. Distinct from the "open and extended" conformation seen in detergent( ), the unliganded TCR-CD3 in nanodiscs adopts two related "closed and compacted" conformations that represent its physiologic resting state . By contrast, the HLA-bound complex adopts the open and extended conformation, and conformation-locking disulfide mutants show that ectodomain opening is necessary for maximal ligand-dependent T-cell activation. Together, these results reveal allosteric conformational change during TCR activation and highlight the importance of native-like lipid environments for membrane protein structure determination. | |||||||||||||||||||||
