== Function == | |||
[[http://www.uniprot.org/uniprot/NUP53_YEAST NUP53_YEAST]] Functions as a component of the nuclear pore complex (NPC). NPC components, collectively referred to as nucleoporins (NUPs), can play the role of both NPC structural components and of docking or interaction partners for transiently associated nuclear transport factors. Active directional transport is assured by both, a Phe-Gly (FG) repeat affinity gradient for these transport factors across the NPC and a transport cofactor concentration gradient across the nuclear envelope (GSP1 and GSP2 GTPases associated predominantly with GTP in the nucleus, with GDP in the cytoplasm). NUP53 may play an important role in cell cycle regulation by inhibiting PSE1 transport functions during mitosis and sequestration of MAD1-MAD2 in a cell cycle-dependent manner. It also seems to play an important role in de novo NPC assembly by associating with nuclear membranes and driving their proliferation.<ref>PMID:9864357</ref> <ref>PMID:11352933</ref> <ref>PMID:12403813</ref> <ref>PMID:12473689</ref> <ref>PMID:14697200</ref> <ref>PMID:12604785</ref> | |||
