CC -!- FUNCTION: Endoribonuclease that catalyzes the hydrolysis of histone-
CC coding pre-mRNA 3'-end. Involved in histone pre-mRNA processing during
CC the S-phase of the cell cycle, which is required for
CC entering/progressing through S-phase. Cleaves histone pre-mRNA at a
CC major and a minor cleavage site after the 5'-ACCCA-3' and the 5'-
CC ACCCACA-3' sequence, respectively, and located downstream of the stem-
CC loop. May require the presence of the HDE element located at the
CC histone pre-RNA 3'-end to avoid non-specific cleavage.
CC {ECO:0000250|UniProtKB:A4D2B0}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a ribonucleotidyl-ribonucleotide-RNA + H2O = a 3'-end
CC ribonucleotide-RNA + a 5'-end (5'-phospho)-ribonucleoside-RNA + H(+);

CC motifs, with two waters completing metal coordination.
CC {ECO:0000250|UniProtKB:A4D2B0}.
CC -!- SIMILARITY: Belongs to the metallo-beta-lactamase superfamily.
