Staphylococcal nuclease domain-containing protein; Endonuclease that mediates miRNA decay of both protein-free and AGO2-loaded miRNAs.

Guanyl-specific ribonuclease pgl-1; Guanyl-specific endoribonuclease which cleaves the phosphodiester bond in single-stranded RNA between the 3'-guanylic residue and the 5'-OH residue of adjacent nucleotide, resulting in the formation of a corresponding 2',3'-cyclic phosphate intermediate. Together with the P-granule component pgl-3, is involved in the formation of P-granules. Together with pgl-3, probably recruits other granule components such as pos-1, mex-3 and glh-1 to P-granules. In addition, may act redundantly with pgl-3 to protect germ cells from excessive germline apoptosis du [...]

ATP-dependent RNA helicase glh-1; Probable ATP-binding RNA helicase. May act redundantly with the P-granule component glh-4 to regulate the formation of the granular structure of P-granules in embryos. May play a role in transgenerational epigenetic inheritance. May protect somatic cells from excessive apoptosis during normal development. Belongs to the DEAD box helicase family. DDX4/VASA subfamily.

NFX1-type zinc finger-containing protein 1 homolog; Epigenetic inheritance factor which, in association with the Argonaute protein wago-4, mediates small RNA-directed transgenerational epigenetic inheritance and thus balances the transgenerational inheritance of epigenetic information. Specifically, maintains a balanced production of small RNAs by preventing the spread of epigenetic signals towards the 5'-end of target mRNAs. Plays a role in small RNA- induced gene silencing in the germline.

Small RNA 2'-O-methyltransferase; Methyltransferase that adds a 2'-O-methyl group at the 3'-end of PIWI-interacting RNAs (piRNAs) and small interfering RNAs (siRNAs) which are classes of regulatory RNAs that are involved in gene silencing in endogenous RNA interference (RNAi) pathways. Methylation protects the 3'-end of small RNAs from tailing and trimming and could constitute a recognition signal for appropriate argonaute machineries (Probable). Methylates and stabilizes 26G-siRNAs (a class of 26 nucleotide siRNAs that possess a monophosphorylated guanine residue at the 5'-end) when t [...]

RNA-directed RNA polymerase related EGO-1.

Death-promoting deoxyribonuclease; Involved in cleaving double-stranded RNA in the RNA interference (RNAi) pathway. It produces 21 to 23 bp dsRNAs (siRNAs) which target the selective destruction of homologous RNAs. Seems to process the precursor of the small temporal RNA let-7 which is involved in developmental timing. Belongs to the helicase family. Dicer subfamily.

Argonaute protein wago-1; Argonaute protein which is involved in the endogenous small interfering RNA (endo-siRNA) pathway. Interacts with secondary 22G- RNAs, which are RNA-dependent RNA polymerase-derived endo-siRNAs, typically 22 nucleotides in length with a 5'guanosine residue. In the germline, functions in a genome surveillance system to silence transposons and aberrant transcripts.

Exonuclease mut-7; Represses the transposition of Tc1, Tc3, Tc4, and Tc5, perhaps by degrading transposon-specific messages. Also affects sperm development, sensitivity to RNAi of mainly germline expressed genes, silencing of some germline transgenes, X chromosome loss, and is required for cosuppression (functional silencing of chromosomal loci induced by transgenes) and for silencing induced by antisense RNA oligomers.
