Protein: Cytoplasmic tRNA 2-thiolation protein 2 (Q55EX7)
Organism: Dictyostelium discoideum (Social amoeba)
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
Subcellular location: Cytoplasm
