CC   -!- FUNCTION: Constitutes one of the two catalytic subunit of the tRNA-
CC       splicing endonuclease complex, a complex responsible for identification
CC       and cleavage of the splice sites in pre-tRNA. It cleaves pre-tRNA at
CC       the 5'- and 3'-splice sites to release the intron. The products are an
CC       intron and two tRNA half-molecules bearing 2',3'-cyclic phosphate and
CC       5'-OH termini. There are no conserved sequences at the splice sites,
CC       but the intron is invariably located at the same site in the gene,
CC       placing the splice sites an invariant distance from the constant
CC       structural features of the tRNA body. Probably carries the active site
CC       for 5'-splice site cleavage. The tRNA splicing endonuclease is also
CC       involved in mRNA processing via its association with pre-mRNA 3'-end
CC       processing factors, establishing a link between pre-tRNA splicing and
CC       pre-mRNA 3'-end formation, suggesting that the endonuclease subunits
CC       function in multiple RNA-processing events (By similarity).
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=pretRNA = a 3'-half-tRNA molecule with a 5'-OH end + a 5'-
CC         half-tRNA molecule with a 2',3'-cyclic phosphate end + an intron with
CC         a 2',3'-cyclic phosphate and a 5'-hydroxyl terminus.; EC=4.6.1.16;
CC   -!- SUBUNIT: tRNA splicing endonuclease is a heterotetramer composed of
CC       TSEN2, TSEN15, TSEN34/LENG5 and TSEN54. tRNA splicing endonuclease
CC       complex also contains proteins of the pre-mRNA 3'-end processing
CC       machinery such as CLP1, CPSF1, CPSF4 and CSTF2 (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Nucleus, nucleolus
CC       {ECO:0000250}. Note=May be transiently localized in the nucleolus.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the tRNA-intron endonuclease family.
CC       {ECO:0000305}.
