SAE1 (SUMO-activating Enzyme Subunit 1, Ubiquitin-like 1-activating Enzyme E1A, AOS1, SUA1, UBLE1A)

SUMO E1 activating enzyme (also called ubiquitin-like activating enzyme E1A, UBLE1A, AOS1, SAE1, and SUA1) is a heterodimeric (SAE1/SAE2)enzyme that activates the ubiquitin-like SUMO proteins (SUMO stands for Small ubiquitin-like modifier.) The SAE1 (SUMO activating enzyme 1, also called Aos1) subunit resembles the N-terminal half of yeast UBA1; the SAE2 (also called Uba2) subunit corresponds to the C-terminal part of yeast UBA1 and contains the active site cysteine. In the SUMO activation step, SAE1/SAE2 uses ATP to adenylate the C-terminal glycine of SUMO-1 (the first of the three different mammalian SUMO proteins) then forms a high-energy thioester bond between the C-terminal glycine and the active site cysteine in SAE2 (Uba2). In the conjugation step, the SUMO moiety is transferred from SAE1/SAE2 to the active site cysteine (Cys 93) of the SUMO conjugating enzyme (SUMO E2, Ubc9) forming a SUMO-E2 thioester complex.\n\nApplications:\nSuitable for use in Immunofluorescence, ELISA and Western Blot. Other applications not tested.\n\nRecommended Dilution:\nELISA: 1:5000-1:20,000\nWestern Blot: 1:500-1:2000\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile dH2O or PBS. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
