CC   -!- FUNCTION: Required for the processing of nuclear mRNA and rRNA
CC       precursors. May promote the termination of transcription by RNA
CC       polymerase II (By similarity). Essential for vegetative cell growth and
CC       chromosome segregation. Possesses 5'->3' exoribonuclease activity.
CC       {ECO:0000250}.
CC   -!- INTERACTION:
CC       P40848; O13836: din1; NbExp=2; IntAct=EBI-15755578, EBI-15755601;
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- SIMILARITY: Belongs to the 5'-3' exonuclease family. XRN2/RAT1
CC       subfamily. {ECO:0000305}.
