SETD8 polyclonal antibody

Protein-lysine N-methyltransferase that monomethylates both histones and non-histone proteins. Specificallymonomethylates 'Lys-20' of histone H4 (H4K20me1). H4K20me1 is enriched during mitosis and represents a specific tagfor epigenetic transcriptional repression. Mainly functions in euchromatin regions, thereby playing a central role inthe silencing of euchromatic genes. Required for cell proliferation, probably by contributing to the maintenance ofproper higher-order structure of DNA during mitosis. Involved in chromosome condensation and proper cytokinesis.Nucleosomes are preferred as substrate compared to free histones. Mediates monomethylation of p53/TP53 at 'Lys-382',leading to repress p53/TP53-target genes.
