UBE2I UBC9 UBCE9 SUMO-conjugating enzyme UBC9 SUMO-protein ligase Ubiquitin carrier protein 9 Ubiquitin carrier protein I Ubiquitin-conjugating enzyme E2 I Ubiquitin-protein ligase I p18
Molecular Weight(MW)
18007 Da
Function
Accepts the ubiquitin-like proteins SUMO1, SUMO2, SUMO3 and SUMO4 from the UBLE1A-UBLE1B E1 complex and catalyzes their covalent attachment to other proteins with the help of an E3 ligase such as RANBP2 or CBX4. Can catalyze the formation of poly- SUMO chains. Necessary for sumoylation of FOXL2 and KAT5 Essential for nuclear architecture and chromosome segregation
Tissue Specificity
Expressed in heart, skeletal muscle, pancreas, kidney, liver, lung, placenta and brain. Also expressed in testis and thymus
Cellular Localization
Nucleus. Cytoplasm. Note=Mainly nuclear. In spermatocytes, localizes in synaptonemal complexes. Recruited by BCL11A into the nuclear body (By similarity)
The anti-UBC9 Mab (Cat. #AM1261b) is used in Western blot to detect UBC9 in HL60 cell lysate.

Storage Instructions
For short-term storage, store at 4° C. For long-term storage, aliquot and store at -20ºC or below. Avoid multiple freeze-thaw cycles.
Storage Buffer
Purified monoclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein G column, eluted with high and low pH buffers and neutralized immediately, followed by dialysis against PBS.
