tRNA-splicing ligase RtcB homolog

Known abbreviations: C22orf28, HSPC117


Catalytic subunit of the tRNA-splicing ligase complex that acts by directly joining spliced tRNA halves to mature-sized tRNAs by incorporating the precursor-derived splice junction phosphate into the mature tRNA as a canonical 3',5'-phosphodiester. May act as a RNA ligase with broad substrate specificity, and may function toward other RNAs. 
ATP + (ribonucleotide)(n) + (ribonucleotide)(m) = AMP + diphosphate + (ribonucleotide)(n+m). 
Catalytic component of the tRNA-splicing ligase complex.
Cytoplasm (By similarity.)
