کاریوفرین

Also known as karyopherin

Karyopherins are transport proteins involved in the nuclear transport of moving molecules between the cytoplasm and the nucleus of a eukaryotic cell. (The inside of the nucleus is called the karyoplasm (or nucleoplasm). Generally, karyopherin-mediated transport occurs through nuclear pores which act as gateways into and out of the nucleus. Macromolecular proteins require karyopherins to traverse the nuclear pore.
