MeSH definition : Nucleocytoplasmic transport molecules that bind to the NUCLEAR LOCALIZATION SIGNALS
of cytoplasmic molecules destined to be imported into the CELL NUCLEUS. Once attached
to their cargo they bind to BETA KARYOPHERINS and are transported through the NUCLEAR
PORE COMPLEX. Inside the CELL NUCLEUS alpha karyopherins dissociate from beta karypherins
and their cargo. They then form a complex with CELLULAR APOPTOSIS SUSCEPTIBILITY PROTEIN
and RAN GTP-BINDING PROTEIN which is exported to the CYTOPLASM.;
