Summary: tRNA-splicing endonuclease subunit sen54 N-term
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
tRNA-splicing endonuclease subunit sen54 N-term Provide feedback
This is an N-terminal family of archaeal and metazoan sen54 proteins that forms one of the tRNA-splicing endonuclease subunits.

tRNA-splicing endonucleases (EC) catalyse the endonucleolytic cleavage of pre tRNA at the 5' and 3' splice sites to release the intron and produces two half tRNA molecules bearing 5' hydroxyl and 2', 3'-cyclic phosphate termini [PUBMED:9321408, PUBMED:9200603]. The genes encoding these proteins are homologous in eukaryotes and archea. The eukaryotic tRNA-splicing endonucleases are heterotetrameric while the archaeal endonucleases can be split into homodimeric and homotetrameric subgroups.This entry represents the N-terminal domain of Sen54, a non-catalytic subunit of the tRNA-splicing endonuclease complex. Defects in human Sen54 are a cause of pontocerebellar hypoplasia type 4 [PUBMED:18711368].

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the UniProtKB sequence database using the family HMM
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
