This gene encodes a 3-5 exoribonuclease that may be involved in the processing of the 12S pre-rRNA. Pseudogenes have been identified on chromosomes 6 and 11. [provided by RefSeq, Dec 2014],function:3-> 5-exoribonuclease involved in ribosome biogenesis in the processing of the 12S pre-rRNA. Displays a strong specificity for a 3-end containing a free hydroxyl group.,similarity:Contains 1 exonuclease domain.,
