Cytoplasmic tRNA 2-thiolation protein 2 (Ctu2)

Plays a central role in 2-thiolation of mcm(5)S(2)U in 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.
