Target Background

Acts as a sulfur carrier required for 2-thiolation of mcm(5)S(2)U at tRNA wobble positions of cytosolic tRNA(Lys), tRNA(Glu) and tRNA(Gln). Serves as sulfur donor in tRNA 2-thiolation reaction by being thiocarboxylated (-COSH) at its C-terminus by MOCS3. The sulfur is then transferred to tRNA to form 2-thiolation of mcm(5)S(2)U. Also acts as a ubiquitin-like protein (UBL) that is covalently conjugated via an isopeptide bond to lysine residues of target proteins such as MOCS3, ATPBD3, CTU2, USP15 and CAS. The thiocarboxylated form serves as substrate for conjugation and oxidative stress specifically induces the formation of UBL-protein conjugates.
Gene References into Functions
  1. ubiquitin-like Urm1.Uba4 systems are conserved and exchangeable between human and yeast cells PMID: 25747390
  2. Urm1 has a conserved dual role by integrating the functions of prokaryotic sulfur carriers with those of eukaryotic protein modifiers of the Ub family PMID: 21209336
  3. observations suggest that Urm1 activation is more similar to that of a prokaryotic sulfur carrier protein than that of a ubiquitin-like protein PMID: 21245332
  4. The UBA4-URM1 system represents the evolutionary link between protein conjugation and protein modification by sulfur carrier proteins. PMID: 18491921
  5. Urm1 is activated by an unusual mechanism to yield a thiocarboxylate intermediate that serves as sulfur donor in tRNA thiolation reactions PMID: 19017811
