CC -!- FUNCTION: Functions in nuclear protein import as an adapter protein for
CC nuclear receptor KPNB1. Binds specifically and directly to substrates
CC containing either a simple or bipartite NLS motif. Docking of the
CC importin/substrate complex to the nuclear pore complex (NPC) is
CC mediated by KPNB1 through binding to nucleoporin FxFG repeats and the
CC complex is subsequently translocated through the pore by an energy
CC requiring, Ran-dependent mechanism. At the nucleoplasmic side of the
CC NPC, Ran binds to importin-beta and the three components separate and
CC importin-alpha and -beta are re-exported from the nucleus to the
CC cytoplasm where GTP hydrolysis releases Ran from importin. The
CC directionality of nuclear import is thought to be conferred by an
CC asymmetric distribution of the GTP- and GDP-bound forms of Ran between
CC the cytoplasm and nucleus. In vitro, mediates the nuclear import of
CC human cytomegalovirus UL84 by recognizing a non-classical NLS. In
CC vitro, mediates the nuclear import of human cytomegalovirus UL84 by
CC recognizing a non-classical NLS.
CC -!- SUBUNIT: Forms a complex with importin subunit beta-1. Interacts with
CC SNAI1. Interacts with TALDO1 isoform 1 (By similarity).

CC -!- SUBUNIT: (Microbial infection) Interacts with MERS virus protein OF4b;

CC -!- SUBUNIT: (Microbial infection) Interacts with human adenovirus 5 E1A
CC protein; this interaction allows E1A import into the host nucleus.
CC {ECO:0000269|PubMed:23864635}.
CC -!- SUBUNIT: (Microbial infection) Interacts with Chikungunya virus capsid
CC protein; this interaction allows the nuclear import of the viral capsid

CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Highly expressed in testis, ovary, small intestine,
CC heart, skeletal muscle, lung and pancreas, but barely detectable in
CC kidney, thymus, colon and peripheral blood leukocytes.
CC -!- DOMAIN: Consists of an N-terminal hydrophilic region, a hydrophobic
CC central region composed of 10 repeats, and a short hydrophilic C-
CC terminus. The N-terminal hydrophilic region contains the importin beta
CC binding domain (IBB domain), which is sufficient for binding importin
CC beta and essential for nuclear protein import.
CC -!- DOMAIN: The IBB domain is thought to act as an intrasteric
CC autoregulatory sequence by interacting with the internal autoinhibitory
CC NLS. Binding of KPNB1 probably overlaps the internal NLS and
CC contributes to a high affinity for cytoplasmic NLS-containing cargo
CC substrates. After dissociation of the importin/substrate complex in the
CC nucleus the internal autohibitory NLS contributes to a low affinity for
CC nuclear NLS-containing proteins (By similarity). {ECO:0000250}.
CC -!- DOMAIN: The major and minor NLS binding sites are mainly involved in
CC recognition of simple or bipartite NLS motifs. Structurally located
CC within in a helical surface groove they contain several conserved Trp
CC and Asn residues of the corresponding third helices (H3) of ARM repeats
CC which mainly contribute to binding (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the importin alpha family. {ECO:0000305}.
CC -!- CAUTION: Was termed importin alpha-3. {ECO:0000305|PubMed:9395085}.
