Ran-binding protein 3 is a protein that in humans is encoded by the RANBP3 gene.[5][6]
This gene encodes a protein with a RanBD1 domain that is found in both the nucleus and cytoplasm. This protein plays a role in nuclear export as part of a heteromeric complex. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.[6]
RANBP3 has been shown to interact with RCC1[5][7] and XPO1.[8][9]
