Gene : AGO7 A. thaliana

Gene ID  ? AT1G69440
Brief Description  Argonaute family protein  Source: Araport11 (06/2016).
Is Obsolete?  false
Computational Description  ? ARGONAUTE7 (AGO7); FUNCTIONS IN: nucleic acid binding; INVOLVED IN: production of ta-siRNAs involved in RNA interference, vegetative phase change, production of lsiRNA involved in RNA interference, regulation of development, heterochronic, gene silencing by miRNA; LOCATED IN: cellular_component unknown; EXPRESSED IN: 18 plant structures; EXPRESSED DURING: 11 growth stages; CONTAINS InterPro DOMAIN/s: Domain of unknown function DUF1785 (InterPro:IPR014811), Stem cell self-renewal protein Piwi (InterPro:IPR003165), Argonaute/Dicer protein, PAZ (InterPro:IPR003100), Polynucleotidyl transferase, ribonuclease H fold (InterPro:IPR012337); BEST Arabidopsis thaliana protein match is: Stabilizer of iron transporter SufD / Polynucleotidyl transferase (TAIR:AT1G48410.1).  Source: TAIR, Jun 30, 2015.
Curator Summary  ? Encodes ARGONAUTE7, a member of the ARGONAUTE family, characterised by the presence of PAZ and PIWI domains. Involved in the regulation of developmental timing. Required for the accumulation of TAS3 ta-siRNAs but not for accumulation of miR171, miR173, miR390 or mi391. Localized in mature rosette leaves and floral buds.  Source: TAIR, Jun 30, 2015.

Annotation PubMed Id
RDR6, SGS3 and AGO7 act in the same pathway, which genetically interacts with the AS1-AS2 pathway for leaf development. 16699177
Study shows that miR390-ARGONAUTE7 complexes function in distinct cleavage or noncleavage modes at two target sites in TAS3a transcripts. 18342362
AGO1 and AGO7 function to ensure efficient clearance of viral RNAs and establish that AGO1 is capable of targeting viral RNAs with more compact structures, whereas AGO7 and RDR6 favor less structured RNA targets 18799732
It was shown that AGO7 is needed in the cytoplasm and membranous siRNA bodies for the processing of the TAS3 precursor, showing a hitherto unknown role for membrane-associated ribonucleoparticles in trans-acting-siRNA biogenesis and AGO action in plants. 22327216
Complementation analyses in ago mutant plants revealed that the catalytic residues of AGO1, AGO2, and AGO7 are required to restore the defects of Arabidopsis ago1-25, ago2-1, and zip-1 (AGO7-defective) mutants, respectively. 23023169
Arabidopsis ARGONAUTE7 selects microRNA390 through multiple checkpoints during RISC assembly. 23732541
