Protein Structure
UniProt Annotation
Function Histone methyltransferase that specifically trimethylates 'Lys-20' of histone H4. H4 'Lys-20' trimethylation represents a specific tag for epigenetic transcriptional repression. Mainly functions in pericentric heterochromatin regions, thereby playing a central role in the establishment of constitutive heterochromatin in these regions. SUV420H1 is targeted to histone H3 via its interaction with RB1 family proteins (RB1, RBL1 and RBL2). {ECO:0000269PubMed:15145825}.
Subcellular Localization Nucleus {ECO:0000269PubMed:15145825}. Chromosome {ECO:0000269PubMed:15145825}. Note=Associated with pericentric heterochromatin. CBX1 and CBX5 are required for the localization to pericentric heterochromatin.
