[[http://www.uniprot.org/uniprot/SUVH4_ARATH SUVH4_ARATH]] Histone methyltransferase. Methylates 'Lys-9' of histone H3. H3 'Lys-9' methylation represents a specific tag for epigenetic transcriptional repression. The silencing mechanism via DNA CpNpG methylation requires the targeting of chromomethylase CMT3 to methylated histones, probably through an interaction with an HP1-like adapter. By its function, KYP is directly required for the maintenance of the DNA CpNpG and asymmetric methylation. Involved in the silencing of transposable elements.<ref>PMID:11898023</ref> <ref>PMID:15457214</ref> <ref>PMID:15598823</ref> <ref>PMID:16277745</ref> <ref>PMID:16287862</ref>
