    Summary
    Predicted to enable several functions, including histone deacetylase binding activity; nuclear import signal receptor activity; and nuclear localization sequence binding activity. Involved in postsynapse to nucleus signaling pathway and regulation of transcription by glucose. Predicted to be located in cytoplasmic stress granule; cytosol; and nucleoplasm. Predicted to be part of NLS-dependent protein nuclear import complex. Predicted to be active in several cellular components, including glutamatergic synapse; nuclear membrane; and postsynaptic density. Orthologous to human KPNA2 (karyopherin subunit alpha 2).

    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.
