Ubiquitin-fold modifier 1 (UbiF), also known as UFM1. is a ubiquitin-like protein involved in post-translational modifications critical for cellular regulation. Discovered in 2004. UbiF shares structural homology with ubiquitin but operates through a distinct conjugation system. It plays a role in endoplasmic reticulum (ER)-associated processes, including stress responses, protein quality control, and ribosome biogenesis. UbiF is activated by a cascade of enzymes: UBA5 (E1-like), UFC1 (E2-like), and UFL1 (E3 ligase), which attach UbiF to target proteins, modulating their function or stability. Dysregulation of the UbiF pathway is linked to developmental disorders, cancer, and neurological conditions like Parkinson’s disease.
Recombinant UbiF proteins are engineered using expression systems (e.g., *E. coli* or mammalian cells) to study its biochemical properties and interactions. These proteins retain post-translational modification capabilities, enabling in vitro studies of UbiF ligation mechanisms. Recombinant UbiF is tagged (e.g., His-tag) for purification and detection, ensuring high yield and purity for structural analyses (e.g., X-ray crystallography) or functional assays. Applications include investigating ER stress pathways, drug discovery targeting UbiF-related diseases, and elucidating its role in autophagy or tumor suppression.
Current research focuses on identifying UbiF-specific substrates and understanding its crosstalk with ubiquitin and other modifiers. Recombinant UbiF tools are pivotal in dissecting its physiological and pathological roles, offering therapeutic potential for disorders tied to proteostasis imbalance.
