Description	Anti-Importin beta-1 Antibody, clone 3H14
Alternate Names	Karyopherin subunit beta-1 Nuclear factor P97 importin 1 importin 90 importin beta-1 subunit karyopherin (importin) beta 1 karyopherin beta 1
Background Information	Importin beta-1 (also known as Importin subunit beta-1) facilitates nuclear protein import. This occurs either though association with a nuclear localization signal (NLS) and an adapter protein , such as an importin-alpha subunit, which which binds to nuclear, or directly where the protein acts as autonomous nuclear transport receptor. Import of macromolecules containing a NLS requires a heterodimer of importin alpha and beta subunits also called as karyopherins. Importin alpha binds the cytoplasmic NLS-containing protein and importin beta docks the complex at the cytoplasmic side of the nuclear pore complex. Movement through the nuclear pore is mediated by the small GTP binding protein Ran via an energy requiring mechanism. Using nucleotide triphosphates and Ran, the nuclear transport complex moves into the nuclear pore and the importin subunits dissociate. Importin alpha and its passenger protein enter the nucleoplasm while importin beta remains at the pore.

Entrez Gene Summary	Nucleocytoplasmic transport, a signal- and energy-dependent process, takes place through nuclear pore complexes embedded in the nuclear envelope. The import of proteins containing a nuclear localization signal (NLS) requires the NLS import receptor, a heterodimer of importin alpha and beta subunits also known as karyopherins. Importin alpha binds the NLS-containing cargo in the cytoplasm and importin beta docks the complex at the cytoplasmic side of the nuclear pore complex. In the presence of nucleoside triphosphates and the small GTP binding protein Ran, the complex moves into the nuclear pore complex and the importin subunits dissociate. Importin alpha enters the nucleoplasm with its passenger protein and importin beta remains at the pore. Interactions between importin beta and the FG repeats of nucleoporins are essential in translocation through the pore complex. The protein encoded by this gene is a member of the importin beta family. [provided by RefSeq].

UniProt Summary	FUNCTION: Functions in nuclear protein import, either in association with an adapter protein, like an importin-alpha subunit, which binds to nuclear localization signals (NLS) in cargo substrates, or by acting as autonomous nuclear transport receptor. Acting autonomously, serves itself as NLS receptor. Docking of the importin/substrate complex to the nuclear pore complex (NPC) is mediated by KPNB1 through binding to nucleoporin FxFG repeats 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 importin-beta and the three components separate and importin-alpha and -beta are re-exported from the nucleus to the cytoplasm where GTP hydrolysis releases Ran from importin. 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. Mediates autonomously the nuclear import of ribosomal proteins RPL23A, RPS7 and RPL5. Binds to a beta-like import receptor binding (BIB) domain of RPL23A. In association with IPO7 mediates the nuclear import of H1 histone. In vitro, mediates nuclear import of H2A, H2B, H3 and H4 histones. In case of HIV-1 infection, binds and mediates the nuclear import of HIV-1 Rev. Imports PRKCI into the nucleus. SUBUNIT STRUCTURE: Forms a complex with an importin alpha subunit.
