This gene encodes a catalytic subunit of the tRNA splicing endonuclease, which catalyzes the removal of introns from precursor tRNAs. The endonuclease complex is also associated with a pre-mRNA 3-prime end processing factor. A mutation in this gene results in the neurological disorder pontocerebellar hypoplasia type 2. Multiple alternatively spliced variants, encoding the same protein, have been identified.[provided by RefSeq, Oct 2009]
GeneCards Summary for TSEN34 Gene
TSEN34 (TSEN34 TRNA Splicing Endonuclease Subunit) is a Protein Coding gene. Diseases associated with TSEN34 include pontocerebellar hypoplasia type 2c and tsen34-related pontocerebellar hypoplasia. Among its related pathways are Gene Expression and tRNA modification in the nucleus and cytosol. GO annotations related to this gene include nucleic acid binding and tRNA-intron endonuclease activity.
UniProtKB/Swiss-Prot for TSEN34 Gene
Constitutes one of the two catalytic subunit of the tRNA-splicing endonuclease complex, a complex responsible for identification and cleavage of the splice sites in pre-tRNA. It cleaves pre-tRNA at the 5- and 3-splice sites to release the intron. The products are an intron and two tRNA half-molecules bearing 2,3-cyclic phosphate and 5-OH termini. There are no conserved sequences at the splice sites, but the intron is invariably located at the same site in the gene, placing the splice sites an invariant distance from the constant structural features of the tRNA body. It probably carries the active site for 3-splice site cleavage. The tRNA splicing endonuclease is also involved in mRNA processing via its association with pre-mRNA 3-end processing factors, establishing a link between pre-tRNA splicing and pre-mRNA 3-end formation, suggesting that the endonuclease subunits function in multiple RNA-processing events.
