This entry includes nucleoporin Nup37, a component of the Nup107-160 subcomplex of the nuclear pore complex (NPC). Nup107-160 is required for assembly of a functional NPC, as well as normal kinetochore microtubule attachment, mitotic progression and chromosome segregation []. The vertebrate Nup107-160 complex includes NUP160, NUP133, NUP107, NUP98, NUP85, NUP43, NUP37, SEH1 and SEC13 []. This entry also includes some uncharacterised fungal proteins.
