PUS3 encodes the human gene, Pseudouridylate synthase 3. It may also be known as: tRNA pseudouridine(38/39) synthase; tRNA pseudouridylate synthase 3; tRNA-uridine isomerase 3; synthase ; tRNA pseudouridine synthase 3; 2610020J05Rik; FKSG32. The encoded protein is an enzyme with an amino acid length of 481 and a mass of 55.6 kDa. PUS3 is a member of the TRNA pseudouridine synthase TruA family. Homologs of this gene exist in other organisms, including: Rat, Zebrafish, Frog, Chicken.
