    Summary
    Predicted to enable nuclear import signal receptor activity and nuclear localization sequence binding activity. Acts upstream of or within negative regulation of muscle cell differentiation and protein import into nucleus. Predicted to be active in cytoplasm and nucleus. Is expressed in several structures, including adrenal gland; alimentary system; gallbladder; genitourinary system; and nervous system. Orthologous to human TNPO2 (transportin 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.
