常规说明
GenBank Accession Number – NP_002259.The nuclear import of karyophilic proteins is directed by short amino acid sequences termed nuclear localization signals (NLSs). Karyopherins, or importins, are cytoplasmic proteins that recognize NLSs and dock NLS-containing proteins to the nuclear pore complex. The protein encoded by this gene shares the sequence similarity with Xenopus importin-alpha and Saccharomyces cerevisiae Srp1. This protein is found to interact with the NLSs of DNA helicase Q1 and SV40 T antigen.
Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.

应用
Our Abpromise guarantee covers the use of ab6039 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
| 应用 | Ab评论 | 说明 |
|---|---|---|
| IHC-P | Use a concentration of 1 - 2 µg/ml. | |
| WB | Use a concentration of 0.2 - 1 µg/ml. Detects a band of approximately 55-60 kDa (predicted molecular weight: 58 kDa). A 1 hour primary incubation is recommended for this product. A customer reported that milk can significantly suppress antigen-antibody interaction on nitrocellulose membrane in WB. |

功能
Functions in nuclear protein import as an adapter protein for nuclear receptor KPNB1. Binds specifically and directly to substrates containing either a simple or bipartite NLS motif. 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. In vitro, mediates the nuclear import of human cytomegalovirus UL84 by recognizing a non-classical NLS. In vitro, mediates the nuclear import of human cytomegalovirus UL84 by recognizing a non-classical NLS. -
组织特异性
Highly expressed in testis, ovary, small intestine, heart, skeletal muscle, lung and pancreas, but barely detectable in kidney, thymus, colon and peripheral blood leukocytes. -
序列相似性
Belongs to the importin alpha family.
Contains 10 ARM repeats.
Contains 1 IBB domain. -
结构域
Consists of an N-terminal hydrophilic region, a hydrophobic central region composed of 10 repeats, and a short hydrophilic C-terminus. The N-terminal hydrophilic region contains the importin beta binding domain (IBB domain), which is sufficient for binding importin beta and essential for nuclear protein import.
The IBB domain is thought to act as an intrasteric autoregulatory sequence by interacting with the internal autoinhibitory NLS. Binding of KPNB1 probably overlaps the internal NLS and contributes to a high affinity for cytoplasmic NLS-containing cargo substrates. After dissociation of the importin/substrate complex in the nucleus the internal autohibitory NLS contributes to a low affinity for nuclear NLS-containing proteins.
The major and minor NLS binding sites are mainly involved in recognition of simple or bipartite NLS motifs. Structurally located within in a helical surface groove they contain several conserved Trp and Asn residues of the corresponding third helices (H3) of ARM repeats which mainly contribute to binding. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-KPNA4 antibody (ab6039)Image is courtesy of an anonymous AbReview.Immunohistochemical analysis of 10% buffered formalin-fixed paraffin-embedded murine nephric tissue sections, labelling KPNA4 with ab6039 at a dilution of 1/100 incubated for 12 hours at 4°C. Heat mediated antigen retrival was performed through 10mM citrate buffer at pH 6.0. Blocking was with 5% serum incubated for 1 hour at 21°C. Secondary was a polyclonal Donkey anti-Goat Alexa Fluor® 647 conjugate at 1/200. Counterstain is DAPI against nuclear DNA. The Negative control is the same as above, but in the abscence of the primary ab6039.
