MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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 this gene 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. Alternative splicing results in multiple transcript variants of this gene. A pseudogene associated with this gene is located on chromosome 6. [provided by RefSeq, May 2013]
PHENOTYPE: Mice homozygous for a gene trap allele die prior to E8.5. Mice homozygous for a gene trap allele exhibit atria fibrillation associated with shortened action potential duration. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to G transition at position 4203 of the Nup155 transcript in exon 35 of 35 total exons. The mutated nucleotide causes a valine to alanine substitution at amino acid 1357 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

 

 

Protein Function and Prediction

The Nup155 gene encodes a 1391 amino acid protein that is an essential component of the nuclear pore complex. Nucleoporins may be involved both in binding and translocating proteins during nucleocytoplasmic transport. The protein is phosphorylated on residues 992 and 994. Phosphorylation and dephosphorylation may be important for the function of NUP155 and may play a role in the reversible disassembly of the nuclear pore complex during mitosis (Uniprot Q99P88). Mice homozygous for a gene trap allele die prior to E8.5. Mice homozygous for a gene trap allele exhibit atria fibrillation associated with shortened action potential duration.

The V1357A change is predicted to be benign by the PolyPhen program.
