    Summary
    The transport of molecules between the nucleus and the cytoplasm in eukaryotic cells is mediated by the nuclear pore complex (NPC) which consists of 60-100 proteins and is probably 120 million daltons in molecular size. Small molecules (up to 70 kD) can pass through the nuclear pore by nonselective diffusion; larger molecules are transported by an active process. Most nuclear proteins contain short basic amino acid sequences known as nuclear localization signals (NLSs). KPNA5 protein belongs to the importin alpha protein family and is thought to be involved in NLS-dependent protein import into the nucleus. [provided by RefSeq, Jul 2008]

    Protein interactions

    Protein Gene Interaction Pubs
    integrase gag-pol HIV-1 IN interacts with importin alpha by the BiFC assay and amino acids 161-173 in IN are required for the interaction with importin alpha PubMed
    gag-pol HIV-1 Rev disrupts both IN-TNPO3 and IN-importin alpha complexes PubMed
    gag-pol Some reports indicate a possible role for the interactions between karyopherin alpha and beta with HIV-1 integrase in the nuclear import of HIV-1 preintegration complexes (PIC), while other reports indicate integrase is not involved in PIC nuclear import PubMed
    gag-pol Karyopherin alpha binds to a bipartite nuclear localization signal in HIV-1 integrase (amino acids 186-189 and 211-219) PubMed
    gag-pol Karyopherin alpha and beta are reported to interact with HIV-1 integrase (IN) to facilitate nuclear import of IN, however a conflicting report indicates nuclear accumulation of IN does not involve karyopherin alpha, beta 1, or beta 2 mediated pathways PubMed
    matrix gag Nuclear import of HIV-1 preintegration complexes by karyopherin alpha is governed by phosphorylation of HIV-1 Matrix on tyrosine and serine, however the exact role of phosphorylation of the C-terminal tyrosine of Matrix has been debated PubMed
    gag HIV-1 Matrix increases intracellular ATP content, an effect hypothesized to support the ATP-dependent nuclear import of HIV-1 preintegration complexes by karyopherin alpha PubMed
    gag HIV-1 Vpr increases the affinity of karyopherin alpha to the HIV-1 Matrix nuclear localization signal, thereby mediating the nuclear import of HIV-1 preintegration complexes PubMed
    gag Hsp70 stimulates the binding of HIV-1 matrix to karyopherin alpha PubMed
    gag The role of HIV-1 Matrix during nuclear import of the HIV-1 preintegration complex has been controversial, however recent understanding indicates HIV-1 Matrix and Vpr proteins act in concert to facilitate nuclear import by binding to karyopherin alpha PubMed
    gag HIV-1 Matrix contains two nuclear localization signals (NLS) spanning amino acids 24-33 and 110-114 that are recognized by karyopherin alpha and mediate the nuclear import of HIV-1 preintegration complexes PubMed

    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.
