F4K1L3_ARATH | function | Possesses 5'->3' exoribonuclease activity. Acts as an endogenous post-transcriptional gene silencing (PTGS) suppressor. |
XRN2_ARATH | function | Possesses 5'->3' exoribonuclease activity (PubMed:11106401). Acts as an endogenous post-transcriptional gene silencing (PTGS) suppressor. Degrades miRNA-derived loops, excised during miRNA maturation in the nucleus (PubMed:17993620). Involved in pre-rRNA processing. Involved in the primary exonucleolytic shortening of the 5' external transcribed spacer (5'ETS), required for endonucleolytic processing at site P by the U3 snoRNP complex. Involved with XRN3 in the 5'-end processing of 5.8S and 25S rRNAs. Contributes with XRN3 to polyadenylation-dependent nuclear RNA surveillance. Involved in the degradation of aberrant polyadenylated pre-rRNA through 5'-end processing (PubMed:20338880). |
F4K1L3_ARATH XRN2_ARATH | similarity | Belongs to the 5'-3' exonuclease family. XRN2/RAT1 subfamily. |
XRN2_ARATH | tissue specificity | Expressed in roots, leaves, stems and flowers. |
