XPO1
Exportin 1 (XPO1), also known as chromosomal maintenance 1 (CRM1), is an eukaryotic protein that mediates the nuclear export of proteins, rRNA, snRNA, and some mRNA.
Function
Exportin 1 mediates leucine-rich nuclear export signal (NES)-dependent protein transport. Exportin 1 specifically inhibits the nuclear export of Rev and U snRNAs. It is involved in the control of several cellular processes by controlling the localization of cyclin B, MPAK, and MAPKAP kinase 2. This protein also regulates NFAT and AP-1.
Interactions
XPO1 has been shown to interact with:
APC,
CDKN1B,
CIITA,
NMD3,
Nucleoporin 62,
RANBP1,
RANBP3,
Ran,
SMARCB1, and
p53.
