Ubiquitin-like modifier-activating enzyme 7 (UBA7), also known as UBE1L, is a member of the E1 ubiquitin-activating enzyme family that plays a critical role in post-translational protein modification. It specifically activates the ubiquitin-like protein ISG15 (interferon-stimulated gene 15) and transfers it to E2 conjugating enzymes, primarily UBE2L6. as part of the ISGylation pathway. This process is tightly linked to type I interferon signaling and innate immune responses, particularly in antiviral defense and tumor suppression. Unlike other E1 enzymes, UBA7 expression is interferon-inducible, positioning it as a key mediator of cellular stress responses.
Recombinant UBA7 protein is generated via heterologous expression systems (e.g., *E. coli* or mammalian cells) to study its enzymatic mechanisms, substrate specificity, and regulatory roles. Structural studies reveal a conserved adenylation domain critical for ATP-dependent activation of ISG15. Dysregulation of UBA7 has been implicated in diseases including lung cancer, where its loss correlates with poor prognosis, and neurodegenerative disorders marked by protein aggregation. Its recombinant form enables *in vitro* assays to screen modulators for therapeutic development. Current research focuses on understanding how UBA7-mediated ISGylation intersects with ubiquitination and other signaling cascades, offering insights into immune evasion mechanisms in viruses and cancer. The protein’s interferon-dependent activity also highlights its potential as a biomarker for inflammatory and autoimmune conditions.
