Fig. 1: Overall structure of human SIDT2.

a A schematic diagram showing the domain organization of SIDT2. SP signal peptide, BRD β-sheet rich domain, TMD transmembrane domain, CTD cytoplasmic domain. The dashed line indicates the unresolved region in the structure. b The overall EM density map of the human SIDT2. SIDT2 is a homodimer, and the protomers A and B are shown in lemon and light blue, respectively. The map was contoured at 0.3 and visualized in ChimeraX (www.cgl.ucsf.edu/chimerax). c Overall structure of SIDT2. The N-linked glycans are displayed as black sticks. All structural figures were prepared in PyMOL (www.pymol.org).
