Ubiquitin Activating Enzyme (E1), also known as A1S9 and UBE1, is responsible for the first step in ubiquitin-protein isopeptide bond formation. E1 catalyzes the activation of the C-terminal carboxyl group of ubiquitin by forming a high-energy thioester bond in an ATP-dependent manner. UBE1 is monomeric and contains two active sites within the E1 molecule, allowing it to bind two ubiquitin moieties at a time, with a new ubiquitin forming an adenylate intermediate as the previous one is transferred to the thiol site. Alternative splicing results in 2 transcript variants encoding the same protein, but with different 5' UTR. Isoform 1 has a different 5' noncoding exon compared to isoform 2. Both variants encode the same protein.Applications:Suitable for use in ELISA, Western Blot and Immunohistochemistry.
