Term Information

Accession: GO:0080188
Name: gene silencing by RNA-directed DNA methylation
Ontology: biological_process
Synonyms: RdDM, RNA-directed DNA methylation
Alternate IDs: None
Definition: A small RNA-based gene silencing process in which small interfering RNAs (siRNAs) guide DNA methylation to the siRNA-generating genomic loci and other loci that are homologous to the siRNAs for de novo DNA methylation. This results in a heterochromatin assembly, a chromatin conformation that is refractory to transcription. In general this process consists of three phases: biogenesis of siRNAs, scaffold RNA production, and the formation of the guiding complex that recruits de novo DNA methyltransferases to the target loci. Transposable elements are silenced by this mechanism. Source: PMID:21420348
Comment: This process has been shown in plants and in yeasts, but so far has not been detected in vertebrates, organisms that lack RNA-dependent RNA polymerase.
