The human C18orf37 protein, now commonly referred to as URI1 (Unconventional prefoldin RPB5 Interactor 1), is a conserved eukaryotic protein encoded by the *URI1* gene located on chromosome 18. Initially identified through its interaction with RNA polymerase II subunit RPB5. URI1 has emerged as a multifunctional scaffold protein involved in diverse cellular processes. Structurally, it contains an N-terminal prefoldin-like domain and a C-terminal CSL zinc finger domain, enabling interactions with molecular chaperones, transcription regulators, and metabolic enzymes.
Functionally, URI1 is implicated in transcriptional regulation, stress response, and mitochondrial homeostasis. It acts as a regulatory component of the R2TP complex, facilitating assembly of macromolecular complexes like mTORC1. linking it to nutrient-sensing pathways. Studies suggest its role in modulating oxidative stress by influencing the activity of enzymes such as PP1γ and AMPK. URI1 has been implicated in cancer progression, metabolic disorders, and neurodegenerative diseases, with overexpression observed in certain malignancies.
Current research focuses on its dual role as a tumor suppressor or oncogene, depending on context, and its potential as a therapeutic target. Its evolutionary conservation underscores its fundamental biological significance, though precise mechanisms remain under investigation. URI1’s interplay with stress pathways and mitochondrial function highlights its importance in maintaining cellular homeostasis under fluctuating metabolic conditions.
