      Background InformationTransportin 1 (Trn1) is a transport receptor that transports substrates from the cytoplasm to the nucleus through nuclear pore complexes by recognizing nuclear localization signals (NLSs). Transportin 1 is a mediator of hnRNP A1 transport into the nucleus.
      Trn1 has two sites for binding NLSs, one with high affinity and second with low affinity. Interactions at the low affinity site controls overall binding affinity. Trn1 recognizes NLSs at the high affinity site followed by a conformational change at the low affinity site that interacts with NLSs. Alternate splicing of the Trn1 gene results in two transcript variants encoding different proteins.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes the beta subunit of the karyopherin receptor complex which interacts with nuclear localization signals to target nuclear proteins to the nucleus. The karyopherin receptor complex is a heterodimer of an alpha subunit which recognizes the nuclear localization signal and a beta subunit which docks the complex at nucleoporins. Alternate splicing of this gene results in two transcript variants encoding different proteins. [provided by RefSeq].

      UniProt Number
      UniProt SummaryFUNCTION: Functions in nuclear protein import as nuclear transport receptor. Serves as receptor for nuclear localization signals (NLS) in cargo substrates. Is thought to mediate docking of the importin/substrate complex to the nuclear pore complex (NPC) through binding to nucleoporin and the complex is subsequently translocated through the pore by an energy requiring, Ran-dependent mechanism. At the nucleoplasmic side of the NPC, Ran binds to the importin, the importin/substrate complex dissociates and importin is re-exported from the nucleus to the cytoplasm where GTP hydrolysis releases Ran. The directionality of nuclear import is thought to be conferred by an asymmetric distribution of the GTP- and GDP-bound forms of Ran between the cytoplasm and nucleus By similarity. Involved in nuclear import of M9-containing proteins. In vitro, binds directly to the M9 region of the heterogeneous nuclear ribonucleoproteins (hnRNP), A1 and A2 and mediates their nuclear import. Appears also to be involved in hnRNP A1/A2 nuclear export. Mediates the nuclear import of ribosomal proteins RPL23A, RPS7 and RPL5. Binds to a beta-like import receptor binding (BIB) domain of RPL23A. In vitro, mediates nuclear import of H2A, H2B, H3 and H4 histones, and SRP19. In case of HIV-1 infection, binds and mediates the nuclear import of HIV-1 Rev.

      SUBUNIT STRUCTURE: Binds HNRPA1, HNRPA2, HNRPDL, RPL23A, RPS7, RPL5, RAN and SRP19. Interacts with H2A, H2B, H3 and H4 histones. Binds to HIV-1 Rev.

      SUBCELLULAR LOCATION: Cytoplasm. Nucleus.

      SEQUENCE SIMILARITIES: Belongs to the importin beta family.

      Contains 8 HEAT repeats.

      Contains 1 importin N-terminal domain.
