Histone-lysine N-methyltransferase SUVR4

UniProtKB accession:  Q8W595

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Histone methyltransferase that converts monomethylated 'Lys-9' of histone H3 (H3K9me1) to dimethylated 'Lys-9' (H3K9me2) in the absence of bound ubiquitin, and to trimethylated 'Lys-9' (H3K9me3) in the presence of bound ubiquitin. Acts in a locus-specific manner and contributes to the transcriptional silencing of pseudogenes and transposons. H3 'Lys-9' methylation represents a specific tag for epigenetic transcriptional repression.
