Protein function: Catalyzes the first step in ubiquitin conjugation to mark cellular proteins for degradation through the ubiquitin-proteasome system (PubMed:1447181, PubMed:1606621, PubMed:33108101). Activates ubiquitin by first adenylating its C-terminal glycine residue with ATP, and thereafter linking this...

MLN7243 is an inhibitor of ubiquitin-activating enzyme (UAE, IC50 = 1 nM). It is selective for UAE over NEDD8-activating enzyme (NAE), SUMO-activating enzyme (SAE), and the autophagy-activating enzyme ATG7 (IC50s = 28, 850, and >10,000 nM, respectively). MLN7243 inhibits proliferation in a panel of 30 cancer cell...

UBA1, the canonical ubiquitin E1 activating enzyme is a 118kDa protein, which forms a homodimer in its active state and catalyzes the first step of the ubiquitin conjugation cascade. It activates ubiquitin in an ATP-dependent mechanism where ATP is hydrolyzed to AMP and PPi, a ubiquitin C-terminal adenylate...

PYZD-4409 is an inhibitor of ubiquitin-activating enzyme (UAE, IC50 = 20 µM in a cell-free assay). It decreases levels of ubiquitinated cell division cycle 34 (Cdc34) in K562 chronic myeloid leukemia (CML) cells when used at a concentration of 50 µM. PYZD-4409 increases levels of cyclin D3 and p53 in HCT116...

Description: TAK-243 (MLN7243) is a selective inhibitor of the ubiquitin-activating enzyme UAE (IC50=1 nM), blocking ubiquitin binding and disrupting both mono-ubiquitin signaling and overall protein ubiquitination. TAK-243 exhibits antitumor activity and promotes apoptosis. Target: Apoptosis, E1/E2/E3 Enzyme,...

Human Ubiquitin Activating Enzyme (E1) (UBE1), also known as UBA1, GenBank Accession No. NM_003334, a.a. 2-1058(end), with N-terminal FLAG-tag, expressed in a Baculovirus infected Sf9 cell expression system, MW=119 kDa.

PYR41 is an irreversible inhibitor of ubiquitin-activating enzyme (E1) with an IC50 value of less than 10 µM. PYR41 specifically inhibits ubiquitin-thioester bond formation (IC50 = 6.4 µM) and not adenylation. It is selective for E1 over ubiquitin-conjugating enzyme (E2) but does inhibit autoubiquitination of the...

NSC 624206 is an inhibitor of ubiquitin-activating enzyme (E1) that specifically blocks ubiquitin-thioester formation (IC50 = 13 µM) but has no effect on ubiquitin adenylation. Through this action, NSC 624206 prevents the ubiquitination and degradation of the tumor suppressor protein p27 in vitro.Formal Name:...

Protein. Human UBA1 (aa12-1058) is fused at the N-terminus to a His-tag. Source: Sf21 cells. Liquid. In 50mM HEPES pH 7.5, 150mM sodium chloride, 10% glycerol, 2mM TCEP. Purity: >95% (SDS-PAGE). UBA1, the canonical ubiquitin E1 activating enzyme is a 118kDa protein, which forms a homodimer in its active state and...
