Biological function summary
Urm1 acts in the thiolation of tRNA and as part of the ubiquitin-related modifier system which affects protein modification and signaling. It plays roles in regulating sulfur metabolism and is important in the biosynthesis of thiolated tRNAs. Urm1 is also involved in oxidative stress response by being part of a complex that modifies proteins in reaction to environmental stressors. As a result Urm1 impacts cellular homeostasis and the stability of various proteins within the cell.
Pathways
Urm1 influences the tRNA modification pathway an important mechanism for proper protein synthesis and function. It also participates in the cellular response to oxidative stress primarily through its interaction with cellular signaling proteins such as ROS-responsive transcription factors. In these pathways Urm1-related conjugations modify proteins affecting their activity during cellular defense mechanisms and the maintenance of protein structure under stress conditions.

General info
Function
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.
Sequence similarities
Belongs to the URM1 family.
Post-translational modifications
C-terminal thiocarboxylation occurs in 2 steps, it is first acyl-adenylated (-COAMP) via the hesA/moeB/thiF part of MOCS3, then thiocarboxylated (-COSH) via the rhodanese domain of MOCS3.
