catalytic activity:2'-phospho-[ligated tRNA] + NAD(+) = mature tRNA + ADP ribose 1'',2''-phosphate + nicotinamide + H(2)O.,function:Catalyzes the last step of tRNA splicing, the transfer of the splice junction 2'-phosphate from ligated tRNA to NAD to produce ADP-ribose 1''-2'' cyclic phosphate.,similarity:Belongs to the kptA/TPT1 family.,tissue specificity:Widely expressed. Weakly or not expressed in lung, spleen, small intestine and peripheral blood leukocytes.,
