SEN15

Gene
sen15
Protein
Probable tRNA-splicing endonuclease subunit sen15
Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843)
Length
143 amino acids
Function
Non-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 (By similarity).
Similarity
Belongs to the SEN15 family.
