Facts about SUMO-conjugating enzyme UBC9.
Accepts the ubiquitin-like proteins SUMO1, SUMO2, SUMO3, SUMO4 and SUMO1P1/SUMO5 from the UBLE1A-UBLE1B E1 complex and catalyzes their covalent attachment to other proteins with the Support of an E3 ligase like RANBP2, CBX4 and ZNF451.
Can catalyze the formation of poly-SUMO chains.Necessary for sumoylation of FOXL2 and KAT5. Essential for nuclear architecture and chromosome segregation.

Expressed in heart, skeletal muscle, pancreas, kidney, liver, lung, placenta and brain. Also expressed in testis and thymus.
Nucleus. Cytoplasm. Mainly nuclear. In spermatocytes, localizes in synaptonemal complexes. Recruited by BCL11A into the nuclear body (By similarity).
