Essential for the progression of premeiotic mitosis and meiosis during sporogenesis. Regulates the cell division of premeiotic germ cells, the proper modification of meiotic chromosomes, and the faithful progression of meiosis, probably via small RNA-mediated gene silencing. May be involved in histone H3 'Lys-9' demethylation in the pericentromeric region. Oryza sativa subsp. japonica (taxid: 39947)
Probably involved in the RNA silencing pathway. May bind to short RNAs such as microRNAs (miRNAs) or short interfering RNAs (siRNAs), and represses the translation of mRNAs which are complementary to them.

>sp|O04379|AGO1_ARATH Protein argonaute 1 OS=Arabidopsis thaliana GN=AGO1 PE=1 SV=1
Involved in RNA-mediated post-transcriptional gene silencing (PTGS). Main component of the RNA-induced silencing complex (RISC) that binds to a short guide RNA such as microRNA (miRNA) or small interfering RNA (siRNA). RISC uses the mature miRNA or siRNA as a guide for slicer-directed cleavage of homologous mRNAs to repress gene expression. Requires DRB1 for directional loading of the small RNA duplex (guide stand and passenger strand) onto RISC for passenger strand degradation. Unlike animal RISC that associates in high molecular weight complex, Arabidopsis RISC is probably composed only of the AGO1 protein and associated RNA without any other proteins. Associates mainly with miRNAs of 21 nucleotide in length and preferentially recruits small RNAs with a 5' terminal uridine. Associates with 22 nucleotide miRNAs to trigger RDR6-dependent secondary siRNAs biogenesis. This pathway amplifies silencing by using the target RNA as substrate to generate secondary siRNAs. Binds to miR168 which targets its own mRNA for repression, establishing a homeostatic regulatory loop. Involved in antiviral RNA silencing by contributing to viral RNA clearance. Is capable of targeting viral RNAs with more compact structures than AGO7 which favors less structured RNA targets. May not associate with 24 nucleotide siRNAs involved in chromatin silencing. Essential for multiple processes in development. Essential for proper development of leaves and floral organs, and formation of axillary meristems. Like AGO10, required for stem cell function and organ polarity.
Probably involved in the RNA silencing pathway. May bind to short RNAs such as microRNAs (miRNAs) or short interfering RNAs (siRNAs), and represses the translation of mRNAs which are complementary to them (By similarity). Plays a role in the maintenance of the indeterminate state of the stem cells in the shoot apical meristem (SAM). Regulates leaf formation through vascular development and may be involved in determining the central domain of the leaf founder region.

Involved in RNA-mediated post-transcriptional gene silencing (PTGS). Main component of the RNA-induced silencing complex (RISC) that binds to a short guide RNA such as a microRNA (miRNA) or small interfering RNA (siRNA). RISC uses the mature miRNA or siRNA as a guide for slicer-directed cleavage of homologous mRNAs to repress gene expression. Required for reliable formation of primary and axillary shoot apical meristems. Specifies leaf adaxial identity by repressing the miR165 and miR166 microRNAs in the embryonic shoot apex, in the shoot apical meristem (SAM) and leaf. Represses the microRNA miR398 which targets CCS1 chaperone mRNAs for translational inhibition. Acts as a negative regulator of AGO1 protein level. Like AGO1, is required for stem cell function and organ polarity. Unlike AGO1, is not subjected to small RNA-mediated repression itself. Essential for multiple processes in development.
Probably involved in the RNA silencing pathway. May bind to short RNAs such as microRNAs (miRNAs) or short interfering RNAs (siRNAs), and represses the translation of mRNAs which are complementary to them.

>PF08699 DUF1785: Domain of unknown function (DUF1785); InterPro: IPR014811 This region is found in argonaute [] proteins and often co-occurs with IPR003103 from INTERPRO and IPR003165 from INTERPRO
PAZ is found in two families of proteins that are essential components of RNA-mediated gene-silencing pathways, including RNA interference, the piwi and Dicer families. PAZ functions as a nucleic-acid binding domain, with a strong preference for single-stranded nucleic acids (RNA or DNA) or RNA duplexes with single-stranded 3' overhangs. It has been suggested that the PAZ domain provides a unique mode for the recognition of the two 3'-terminal nucleotides in single-stranded nucleic acids and buries the 3' OH group, and that it might recognize characteristic 3' overhangs in siRNAs within RISC (RNA-induced silencing) and other complexes. This parent model also contains structures of an archaeal PAZ domain.
Argonaute is part of the RNA-induced silencing complex (RISC), and is an endonuclease that plays a key role in the RNA interference pathway. The PAZ domain has been named after the proteins Piwi,Argonaut, and Zwille.

>PF02170 PAZ: PAZ domain; InterPro: IPR003100 This domain is named after the proteins Piwi Argonaut and Zwille
It is also found in the CAF protein from Arabidopsis thaliana. The function of the domain is unknown but has been found in the middle region of a number of members of the Argonaute protein family, which also contain the Piwi domain (IPR003165 from INTERPRO) in their C-terminal region []. Several members of this family have been implicated in the development and maintenance of stem cells through the RNA-mediated gene-quelling mechanisms associated with the protein DICER. ; GO: 0005515 protein binding; PDB: 1R6Z_P 1T2R_A 1T2S_A 3MJ0_A 1VYN_A 3O3I_X 2L5C_A 3O6E_X 3O7V_X 2L5D_A ....
