Web24 apr 2024 · 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. The octameric TCR-CD3 complex is assembled with 1:1:1:1 stoichiometry of TCRαβ:CD3γε:CD3δε:CD3ζζ. Il fine ultimo delle cascate di trasduzione del segnale è quello di attivare dei fattori di trascrizione che aumentino o inizino la produzione di proteine specifiche. Nei linfociti T sono 3 i principali fattori che vengono attivati: • AP-1: è un dimero formato dalle proteine Fos e Jun legate fra loro tramite un motivo a cerniera di leucina.
