23/Karyopherin β

Using nuclear import assays, several cytosolic proteins that form a multi-protein complex have been identified. These proteins of 54 kDa, 56 kDa, and 97 kDa stimulate the nuclear transport of proteins containing a nuclear localization signal (NLS). The 97 kDa protein has been named karyopherin β. The NLS binds to karyopherin α. Binding is enhanced by karyopherin β. The NLS substrate also binds to the N-terminal region of karyopherin β. Both karyopherins bind to repeat sequences of nucleoporins at the nuclear envelope. Once the substrate is docked to the nuclear envelope, Ran hydrolyzes GTP and translocation occurs. Karyopherin β also binds to and inhibits the Ran GTPase protein, thus providing a mechanism of nuclear transport termination.

This antibody is routinely tested by western blot analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

Format Details
Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
