TRNA splicing endonuclease subunit 54 is a protein that in humans is encoded by the TSEN54 gene. [1]


This gene encodes a subunit of the tRNA splicing endonuclease complex, which catalyzes the removal of introns from precursor tRNAs. The complex is also implicated in pre-mRNA 3-prime end processing.

Clinical significance

Mutations in this gene result in pontocerebellar hypoplasia type 2.
