== Function ==

[https://www.uniprot.org/uniprot/KMT5A_HUMAN KMT5A_HUMAN] Protein-lysine N-methyltransferase that monomethylates both histones and non-histone proteins. Specifically monomethylates 'Lys-20' of histone H4 (H4K20me1). H4K20me1 is enriched during mitosis and represents a specific tag for epigenetic transcriptional repression. Mainly functions in euchromatin regions, thereby playing a central role in the silencing of euchromatic genes. Required for cell proliferation, probably by contributing to the maintenance of proper 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. Plays a negative role in TGF-beta response regulation and a positive role in cell migration.<ref>PMID:12086618</ref> <ref>PMID:12121615</ref> <ref>PMID:15200950</ref> <ref>PMID:15933069</ref> <ref>PMID:15933070</ref> <ref>PMID:16517599</ref> <ref>PMID:17707234</ref> <ref>PMID:23478445</ref>

== Publication Abstract from PubMed ==
 +
Selective inhibitors of protein lysine methyltransferases, including SET domain-containing protein 8 (SETD8), are highly desired, as only a fraction of these enzymes are associated with high-quality inhibitors. From our previously discovered SETD8 inhibitor, we developed a more potent analog and solved a cocrystal structure, which is the first crystal structure of SETD8 in complex with a small-molecule inhibitor. This cocrystal structure allowed the design of a covalent inhibitor of SETD8 (MS453), which specifically modifies a cysteine residue near the inhibitor binding site, has an IC50 value of 804 nM, reacts with SETD8 with near-quantitative yield, and is selective for SETD8 against 28 other methyltransferases. We also solved the crystal structure of the covalent inhibitor in complex with SETD8. This work provides atomic-level perspective on the inhibition of SETD8 by small molecules and will help identify high-quality chemical probes of SETD8.
