NUP155 (Nucleoporin 155) is a Protein Coding gene. Diseases associated with NUP155 include Atrial Fibrillation 15 and Familial Atrial Fibrillation. Among its related pathways are Transport of the SLBP independent Mature mRNA and Cell Cycle, Mitotic. Nucleoporins are proteins that play an important role in the assembly and functioning of the nuclear pore complex (NPC) which regulates the movement of macromolecules across the nuclear envelope (NE). The protein encoded by NUP155 plays a role in the fusion of NE vesicles and formation of the double membrane NE. The protein may also be involved in cardiac physiology and may be associated with the pathogenesis of atrial fibrillation.
