E3 SUMO-protein ligase RanBP2 (RANBP2)

E3 SUMO-protein ligase which Eases SUMO1 and SUMO2 conjugation by UBE2I (PubMed:11792325, PubMed:12032081, PubMed:15378033, PubMed:22194619, PubMed:15931224).

Involved in transport factor (Ran-GTP, karyopherin)-mediated protein import through the F-G repeat-containing domain which acts as a docking site for substrates (PubMed:7775481).

May bind DNA (PubMed:7775481). Component of the nuclear export pathway (PubMed:10078529).
