CC   -!- FUNCTION: Catalyzes the conversion of 3'-phosphate to a 2',3'-cyclic
CC       phosphodiester at the end of RNA. The mechanism of action of the enzyme
CC       occurs in 3 steps: (A) adenylation of the enzyme by ATP; (B) transfer
CC       of adenylate to an RNA-N3'P to produce RNA-N3'PP5'A; (C) and attack of
CC       the adjacent 2'-hydroxyl on the 3'-phosphorus in the diester linkage to
CC       produce the cyclic end product. The biological role of this enzyme is
CC       unknown but it is likely to function in some aspects of cellular RNA
CC       processing (By similarity). {ECO:0000250|UniProtKB:O00442}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 3'-end 3'-phospho-ribonucleotide-RNA + ATP = a 3'-end 2',3'-
CC         cyclophospho-ribonucleotide-RNA + AMP + diphosphate;

CC   -!- SUBUNIT: Monomer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus, nucleoplasm
CC       {ECO:0000250|UniProtKB:O00442}.
CC   -!- SIMILARITY: Belongs to the RNA 3'-terminal cyclase family. Type 1
CC       subfamily. {ECO:0000305}.
