Cellular Localisation: Cytoplasm. Mitochondrion. Nucleus [Isoform 2]: Cytoplasm

Molecular Weight: 117849

Clone: Polyclonal

Gene Name: UBA1

Gene ID: 7317

Function: Catalyzes the first step in ubiquitin conjugation to mark cellular proteins for degradation through the ubiquitin-proteasome system (PubMed:1606621, PubMed:1447181, PubMed:33108101) . 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) .

Summary: Tissue Location: Detected in erythrocytes (at protein level) . Ubiquitous.

Form: Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification.

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.

Application: WB, IHC-P

Dilution: WB--1:1000 IHC-P--1:100~500
