一次抗体 備考
The accumulation of proteins in the nucleus is mediated by short sequences of basic amino acids called nuclear localization sequences (NLSs). These sequences are necessary and sufficient to direct a protein or inert carrier to the nuclear interior. Nuclear protein import is accomplished by two sequential, energy dependent events. The first step, docking at the nuclear pore complex, requires a 54/56 kDa nuclear localization signal receptor (a-karyopherin, importin-a, SRP-a) and the nuclear transport factor p97 (NTF 97, b-karyopherin, importin-b). The second step, translocation across the nuclear envelope (NE), requires the GTP-binding protein, Ran/TC4. -

機能
Functions in nuclear protein import, either in association with an adapter protein, like an importin-alpha subunit, which binds to nuclear localization signals (NLS) in cargo substrates, or by acting as autonomous nuclear transport receptor. Acting autonomously, serves itself as NLS receptor. 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. Mediates autonomously the nuclear import of ribosomal proteins RPL23A, RPS7 and RPL5. Binds to a beta-like import receptor binding (BIB) domain of RPL23A. In association with IPO7 mediates the nuclear import of H1 histone. In vitro, mediates nuclear import of H2A, H2B, H3 and H4 histones. In case of HIV-1 infection, binds and mediates the nuclear import of HIV-1 Rev. Imports PRKCI into the nucleus. -

NIH/3T3 (Mouse embryo fibroblast cell line) cells were incubated for 4 minutes in PHEM/1%triton, washed for 2 minutes in 1x PHEM and fixed for 10 minutes at room temperature in 3.7% PFA containing 30mM sucrose. Following washing in PBS, the cells were incubated for 2 minutes in 100% Methanol at -20°C, then washed 3 times in PBS. The cells were then incubated with ab2811 (1/200) for 1 hour at room temperature. The image panel shows the nuclei stained with DAPI (blue) and the nuclear envalope and cytoplasm stained with ab2811 (green). 100x magnification.

Immunoprecipitation of Importin beta, in HeLa (Human epithelial cell line from cervix adenocarcinoma) cells, using ab2811. Coomassie-stained 8% SDS-page gel was loaded with IP fractions obtained by incubating 2 mg of pre-cleared HeLa whole cell extracts with 4µg ab2811 or 4µg IgG (control). The Importin band (see arrow) was cut out of the gel and its identity confirmed by Mass Spectometry. Please refer to protocol tab for further experimental details.

Cells were blocked with a 2% solution of BSA-PBS for 30 min at room temperature and incubated with ab2811 (1ug/test) for 40 min at room temperature. Cells were then incubated for 40 min at room temperature in the dark using a Dylight 488-conjugated secondary antibody and re-suspended in PBS for FACS analysis.
