From Wikipedia, the free encyclopedia
Karyopherins are a group of proteins involved in transporting molecules through the pores of the nuclear envelope (the membrane around a cell's nucleus.
Karyopherins, which may act as importins or exportins, are part of the Importin-β super-family which all share a similar three-dimensional structure.
