Here, we report the cryo\u2013electron microscopy structures of five distinct conformations of the human NaS1 at resolutions of 2.7 to 3.3 angstroms, revealing the substrates recognition mechanism and the conformational change of NaS1 during the Na\n            <jats:sup>+<\/jats:sup>\n            -sulfate cotransport cycle.
