URMylation Signaling Pathway in Cancer: Molecular Mechanisms and Therapeutic Opportunities
Ubiquitin-related modifier 1 (URM1) defines a distinctive ubiquitin-like system in which URM1 functions both as a covalent protein modifier and a sulfur carrier required for wobble uridine (U34) thiolation of cytosolic tRNAs. This dual role places URM1 signaling at the intersection of protein post-translational modific...
