Overlay histogram showing Jurkat cells stained with ab2811 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab2811, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 2μg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Jurkat cells fixed with methanol (5 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.

Biological function summary
Importin beta facilitates the import of nuclear localization signal (NLS)-bearing proteins into the nucleus. KPNB1 forms a complex with importin alpha to mediate import processes. Importin alpha binds to the NLS-containing cargo while KPNB1 interacts with the nuclear pore complex. This system oversees important regulation of several cellular processes including signal transduction and cell cycle progression. The protein's role helps to organize cellular response to various stimuli maintaining cellular homeostasis.
Pathways
KPNB1 contributes to regulation in the nuclear import and export pathways. It tightly associates with Ran-GTPase a protein involved in the Ran pathway. This interaction supports directionality and specificity of energy-dependent nuclear transport. Additionally KPNB1 associates with proteins like NUP50 and NUP98 functioning as a gatekeeper at the nuclear pore complex by controlling cargo passage. Through these pathways KPNB1 balances cellular imports and exports critical for cell health and functionality.
