Source Description
UniProtInvolved in RNA-directed DNA methylation (RdDM). Required for the silencing of some endogenous RdDM targets and accumulation of 24-nt siRNAs, but not for the production of Pol V-dependent transcripts. Functions in transcriptional silencing through both DNA methylation-dependent and -independent pathways. Required for both maintenance and de-novo DNA methylation. Plays a role in the recruitment of Pol IV to genomic regions associated with K9 methylated histone H3 that are targets for RdDM. {ECO:0000269|PubMed:21811420, ECO:0000269|PubMed:22064704, ECO:0000269|PubMed:23636332, ECO:0000269|PubMed:23637343}.
