NCBI and Uniprot Product Information
NCBI Description
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. [provided by RefSeq, Jul 2008]
Uniprot Description
KPNA4: an alpha importin protein that 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. Forms a complex with importin beta-1 subunit.

Product Notes
The KPNA4 kpna4 (Catalog #AAA6424152) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The KPNA4 (Karyopherin alpha 4, Importin alpha 3, QIP1, SRP3, IPOA3) (PE) reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's KPNA4 can be used in a range of immunoassay formats including, but not limited to, Immunofluorescence (IF), Western Blot (WB), Immunohistochemistry (IHC). IF: 1:50-1:200 WB: 1:500-1:2000 IHC: 1:50-1:200 Applications are based on unconjugated antibody. Researchers should empirically determine the suitability of the KPNA4 kpna4 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "KPNA4, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
