The E1 Ubiquitin Activating Enzyme 1 also known as UBA1 performs the initial step in the ubiquitination process. This enzyme activates ubiquitin a small protein that tags other proteins for degradation by the proteasome. UBA1 binds to ubiquitin in an ATP-dependent manner facilitating its transfer to E2 ubiquitin-conjugating enzymes. UBA1 has a molecular mass of approximately 117 kDa and shows expression in various tissues particularly in actively dividing cells.

Biological function summary

The enzyme plays an essential role in protein homeostasis by initiating the ubiquitin-proteasome system. UBA1 actively contributes to cellular regulation by targeting damaged or misfolded proteins for degradation thereby maintaining protein quality control. The enzyme is part of a complex alongside other proteins involved in the ubiquitination pathway which include E2 enzymes and E3 ubiquitin ligases that work together to achieve selective protein ubiquitination.

Pathways

E1 Ubiquitin Activating Enzyme 1 functions centrally in the ubiquitin-proteasome pathway a major mechanism governing protein turnover. It cooperates with other enzymes such as E2 and E3 to form a cascade that ensures substrate specificity and timely degradation. The enzyme also connects to the NF-kB signaling pathway where it regulates the stability of inhibitor kB proteins influencing immune responses and inflammation processes.

Mutations or dysregulation of UBA1 contribute to spinal muscular atrophy (SMA) and X-linked spinal muscular atrophy (XL-SMA). These conditions involve motor neuron degeneration linked to the impaired ubiquitin-proteasome function. Additionally alterations in UBA1 activity can impact B-cell-activation through the NF-kB pathway possibly leading to autoimmune disorders. Understanding the interactions of UBA1 with associated proteins provides insight into potential therapeutic targets for treating these diseases.

Target data

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 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).
