Not yet tested in other applications. Concentration 1 mg/ml Reactive Species Human,Mouse,Rat Host Species Rabbit Immunogen Synthesized peptide derived from the N-terminal region of human Karyopherin α2. Specificity Karyopherin α2 Polyclonal Antibody detects endogenous levels of Karyopherin α2 protein. Purification The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen Form Liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide. Gene Name KPNA2 Accession No. P52292 P52293 Alternate Names KPNA2; RCH1; SRP1; Importin subunit alpha-2; Karyopherin subunit alpha-2; RAG cohort protein 1; SRP1-alpha Description karyopherin subunit alpha 2(KPNA2) Homo sapiens The import of proteins into the nucleus is a process that involves at least 2 steps. The first is an energy-independent docking of the protein to the nuclear envelope and the second is an energy-dependent translocation through the nuclear pore complex. Imported proteins require a nuclear localization sequence (NLS) which generally consists of a short region of basic amino acids or 2 such regions spaced about 10 amino acids apart. Proteins involved in the first step of nuclear import have been identified in different systems. These include the Xenopus protein importin and its yeast homolog, SRP1 (a suppressor of certain temperature-sensitive mutations of RNA polymerase I in Saccharomyces cerevisiae), which bind to the NLS. KPNA2 protein interacts with the NLSs of DNA helicase Q1 and SV40 T antigen and may be involved in the nuclear transport of proteins. KPNA2 also may play a role in V(D)J re Protein Expression Bone marrow,Cervix carcinoma,Epithelium,Hepatoma,Liver,Mammary cancer,Testi Subcellular Localization nucleus,nuclear pore,nucleoplasm,cytoplasm,cytosol,membrane, Protein Function domain: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.,domain: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.,domain: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.,function: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.,mass spectrometry: PubMed:11840567,similarity:Belongs to the importin alpha family.,similarity:Contains 1 IBB domain.,similarity:Contains 10 ARM repeats.,subunit:Forms a complex with importin subunit beta-1. Found in a complex with CSE1L/XPO2, Ran and KPNA2. Interacts with CSE1L/XPO2 and NBN. Interacts with ANP32E (By similarity). Interacts with HIV-1 Vpr and PLAG1.,tissue specificity:Expressed ubiquitously., Usage For Research Use Only! Not for diagnostic or therapeutic procedures. - Reviews
