Function Plays a central role in 2-thiolation of mcm(5)S(2)U at tRNA wobble positions of tRNA(Lys), tRNA(Glu) and tRNA(Gln). May act by forming a heterodimer with CTU1/ATPBD3 that ligates sulfur from thiocarboxylated URM1 onto the uridine of tRNAs at wobble position. {ECO:0000255|HAMAP-Rule:MF_03054, ECO:0000269|PubMed:19017811}.
Pathway tRNA modification; 5-methoxycarbonylmethyl-2-thiouridine- tRNA biosynthesis. {ECO:0000255|HAMAP-Rule:MF_03054}.
Similarity Belongs to the CTU2/NCS2 family. {ECO:0000255|HAMAP- Rule:MF_03054}.
Subcellular Location Cytoplasm.
Subunit Component of a complex at least composed of URM1, CTU2/NCS2 and CTU1/ATPBD3. {ECO:0000255|HAMAP-Rule:MF_03054, ECO:0000269|PubMed:19017811}.
