|Other Accession||Q5U300, Q29504, Q02053, A3KMV5|
|Predicted||Rat, Rabbit, Bovine|
|Other Names||Ubiquitin-like modifier-activating enzyme 1, Protein A1S9, Ubiquitin-activating enzyme E1, UBA1, A1S9T, UBE1|
|Target/Specificity||This E1 Ubiquitin (UBE1) antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 1026-1058 amino acids from the C-terminal region of human E1 Ubiquitin (UBE1).|
|Format||Purified polyclonal 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.|
|Storage||Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||E1 Ubiquitin (UBE1) Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Catalyzes the first step in ubiquitin conjugation to mark cellular proteins for degradation through the ubiquitin- proteasome system (PubMed:1606621, PubMed:1447181). Activates ubiquitin by first adenylating its C-terminal glycine residue with ATP, and thereafter linking this residue to the side chain of a cysteine residue in E1, yielding a ubiquitin-E1 thioester and free AMP (PubMed:1447181). Essential for the formation of radiation- induced foci, timely DNA repair and for response to replication stress. Promotes the recruitment of TP53BP1 and BRCA1 at DNA damage sites (PubMed:22456334).|
|Cellular Location||Cytoplasm. Mitochondrion. Nucleus Isoform 2: Cytoplasm|
|Tissue Location||Detected in erythrocytes (at protein level). Ubiquitous.|

UBE1 catalyzes the first step in ubiquitin conjugation to mark cellular proteins for degradation. This gene complements an X-linked mouse temperature-sensitive defect in DNA synthesis, and thus may function in DNA repair. It is part of a gene cluster on chromosome Xp11.23. Alternative splicing results in 2 transcript variants encoding the same protein, but with different 5' UTR.
