Exportin/Importin, Cse1-like (IPR013713)

Short name: Cse1

Overlapping homologous superfamilies

Domain relationships



The exchange of macromolecules between the nucleus and cytoplasm takes place through nuclear pore complexes within the nuclear membrane. Active transport of large molecules through these pore complexes require carrier proteins, called karyopherins (importins and exportins), which shuttle between the two compartments.

This domain is found in exportin Cse1 (also known as importin-alpha re-exporter). Exportin Cse1 mediates nuclear transport of importin-alpha back into the cytosol, where importin-alpha functions as a transporter of proteins carrying nuclear localisation signals (NLS) from the cytoplasm into the nucleus [PMID: 15602554, PMID: 15866177, PMID: 17170104]. This domain contains HEAT repeats.
