GeneCards Summary for CTU2 Gene

CTU2 (Cytosolic Thiouridylase Subunit 2 Homolog (S. Pombe)) is a Protein Coding gene. Diseases associated with CTU2 include exotropia. Among its related pathways are Sulfur relay system.

UniProtKB/Swiss-Prot for CTU2 Gene

  • 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.
