Event=Alternative splicing; Named isoforms=3; Name=1; IsoId=Q2VPK5-1; Sequence=Displayed; Name=2; IsoId=Q2VPK5-3; Sequence=VSP_025950; Note=No experimental confirmation available.; Name=3; IsoId=Q2VPK5-5; Sequence=VSP_039378; Note=Incomplete sequence.;
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}.
