Scientific Background: UBA2 (SAE2) or ubiquitin-like modifier activating enzyme 2 forms a heterodimer that functions as a SUMO-activating enzyme for the sumoylation of proteins. The posttranslational modification of proteins by the addition of the small protein SUMO or sumoylation, regulates protein structure and intracellular localization (1). UBA2 functions in SUMO1 activation in a manner analogous to the single E1 ubiquitin-activating enzymes (2). The inactivation of UBA2 may be a therapeutic strategy in MYC-driven cancers.

NCBI and Uniprot Product Information
NCBI Description
Posttranslational modification of proteins by the addition of the small protein SUMO (see SUMO1; MIM 601912), or sumoylation, regulates protein structure and intracellular localization. SAE1 (MIM 613294) and UBA2 form a heterodimer that functions as a SUMO-activating enzyme for the sumoylation of proteins (Okuma et al., 1999 [PubMed 9920803]).[supplied by OMIM, Mar 2010]
Uniprot Description
Function: The heterodimer acts as a E1 ligase for SUMO1, SUMO2, SUMO3, and probably SUMO4. It mediates ATP-dependent activation of SUMO proteins followed by formation of a thioester bond between a SUMO protein and a conserved active site cysteine residue on UBA2/SAE2. Ref.11 Ref.12 Ref.16 Ref.22 Ref.23 Ref.24
Pathway: Protein modification; protein sumoylation.
Subunit structure: Heterodimer of SAE1 and UBA2/SAE2. The heterodimer corresponds to the two domains that are encoded on a single polypeptide chain in ubiquitin-activating enzyme E1. Interacts with UBE2I. Ref.11 Ref.16 Ref.22 Ref.23 Ref.24
Subcellular location: Cytoplasm. Nucleus. Note: Shuttles between the cytoplasm and the nucleus, sumoylation is required either for nuclear translocation or nuclear retention. Ref.11 Ref.21
Post-translational modification: Sumoylated with SUMO1 and SUMO2/3 and by UBC9. Sumoylation at Lys-236 inhibits enzymatic activity. Sumoylation at the C-terminal lysine cluster plays an essential role in nuclear trafficking. Ref.20 Ref.21
Sequence similarities: Belongs to the ubiquitin-activating E1 family.

Product Notes
The UBA2 (SAE2) uba2 (Catalog #AAA515344) is a Recombinant Protein produced from Sf9 insect cells and is intended for research purposes only. The product is available for immediate purchase. The tag for this protein is GST tag!!Expression System||Sf9 insect cells using baculovirus!!Source Note||Recombinant full-length human UBA2 (SAE2) was expressed by baculovirus in Sf9 insect cells. AAA Biotech's UBA2 (SAE2) can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). Researchers should empirically determine the suitability of the UBA2 (SAE2) uba2 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "UBA2 (SAE2), Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
