General description

The importin alpha/beta heterodimer facilitates the translocation of hundreds of proteins across the nuclear envelope. Importin alpha binds to proteins containing a classical nuclear localization signal and links them to importin beta ((KPNB1), a protein which ferries the complex through the nuclear pore complex. Movement through the nuclear pore is mediated by the small GTP binding protein Ran via an energy requiring mechanism. Using nucleotide triphosphates and Ran, the nuclear transport complex moves into the nuclear pore and the importin subunits dissociate. Importin alpha and its passenger protein enter the nucleoplasm while importin beta remains at the pore.


This antibody recognizes Importin subunit alpha-1.
