What's a GeneRIF?

a decreased H7N9 influenza A virus polymerase activity when importin-alpha7 was silenced by siRNA, is reported.
Title: H7N9 Influenza A Virus Exhibits Importin-α7-Mediated Replication in the Mammalian Respiratory Tract.
a novel importin alpha family member with distinct subcellular localization and nuclear localization signal binding characteristics
Title: Karyopherin alpha7 (KPNA7), a divergent member of the importin alpha family of nuclear import receptors.
knocking out of Kpna7 induced abnormalities of gene expression (dppa2, dppa4, and piwil2) and epigenetic modifications (down-regulation of histone H3K27me3). Biochemical analysis showed that KPNA7 interacts with KPNB1 (importin-beta1).
Title: Novel importin-alpha family member Kpna7 is required for normal fertility and fecundity in the mouse.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
