== Function == | |||
[[http://www.uniprot.org/uniprot/XRN2_CAEEL XRN2_CAEEL]] Possesses 5'->3' exoribonuclease activity. Plays a role in maintenance of steady-state concentration and turnover of microRNAs (miRNA) by degradation of mature miRNA. Partially redundant to xrn-1 in miRNA guide strand degradation. Implicated in differential regulation of mRNAs such as let-7 by controlling the accumulation of mature miRNA. Positively regulates molting of the pharyngeal cuticle.<ref>PMID:19734881</ref> <ref>PMID:21397849</ref> | |||
