9.A.75.1.1
The MHCII complex of three proteins, DQ alpha-1, DQ beta-1 (which form a heterodimer) and a CD75 homotrimer that together form a nanomer with 3 copies of the MHCII dimer. It transports antigenic peptides to the cell surface (Wosen et al. 2018). The structure, topology, and dynamics of membrane-inserted polypeptides and lipids have been examined by solid-state NMR spectroscopy, specifically with respect to the transmembrane domains of the DQ Beta-1 subunit of the MHC II receptor and the COP I protein, p24 (Salnikov et al. 2019).
