Human Gene CTU2 (uc002flm.3) Description and Page Index
  Description: Homo sapiens cytosolic thiouridylase subunit 2 homolog (S. pombe) (CTU2), transcript variant 1, mRNA.
RefSeq Summary (NM_001012759): This gene encodes a protein which is involved in the post-transcriptional modification of transfer RNAs (tRNAs). The encoded protein plays a role in thiolation of uridine residue present at the wobble position in a subset of tRNAs, resulting in enhanced codon reading accuracy. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jan 2016].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=Cytoplasmic tRNA 2-thiolation protein 2;
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.
PATHWAY: tRNA modification; 5-methoxycarbonylmethyl-2-thiouridine- tRNA biosynthesis.
SUBUNIT: Component of a complex at least composed of URM1, CTU2/NCS2 and CTU1/ATPBD3.
SIMILARITY: Belongs to the CTU2/NCS2 family.

ModBase Predicted Comparative 3D Structure on Q2VPK5
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
