RT required for proper chromosome segregation in fission yeast.";
RL Nucleic Acids Res. 29:1326-1333(2001).
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}.
