N-lysine methyltransferase KMT5A (UniProt: Q9NQR1; also known as EC: 2.1.1.43, H4-K20-HMTase KMT5A, Histone-lysine N-methyltransferase KMT5A, Lysine N-methyltransferase 5A, Lysine-specific methylase 5A, PR/SET domain-containing protein 07, PR-Set7, PR/SET07, SET domain-containing protein 8) is encoded by the KMT5A (also known as PRSET7, SET07, SET8, SETD8) gene (Gene ID: 387893) in human. SETD8 (hPR-SET7) is a histone methyltransferase that adds a single methyl group to lysine 20 of histone H4 (H4K20me1). H4K20me1 is enriched during mitosis and represents a specific tag for epigenetic transcriptional repression. SETD8 is not detected during the G1 phase. It is first detected during S through G2 phases, and peaks during mitosis. It mainly functions in euchromatin regions, thereby playing a central role in the silencing of euchromatic genes. It is required for cell proliferation, probably by contributing to the maintenance of proper higher-order structure of DNA during mitosis and is also involved in chromosome condensation and proper cytokinesis. It is also reported to mediate mono-methylation of p53/TP53 at lysine 382, leading to repress p53/TP53-target genes. SETD8 has a SET domain in the amino acids 257-378 and this region contains the active site of enzymatic activity. Sequences upstream and downstream of SET domain are also required for its methyltransferase activity. Two isoforms of SETD8 have been described that are produced by alternative splicing.

Function: Histone methyltransferase that specifically monomethylates 'Lys-20' of histone H4. H4 'Lys-20' monomethylation 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. Catalytic activity: S-adenosyl-L-methionine + histone L-lysine = S-adenosyl-L-homocysteine + histone N(6)-methyl-L-lysine. Subcellular location: Nucleus. Note: Specifically localizes to mitotic chromosomes. Associates with silent chromatin on euchromatic arms. Not associated with constitutive heterochromatin. Developmental stage: Not detected during G1 phase. First detected during S through G2 phases, and peaks during mitosis (at protein level). Induction: By HCFC1 C-terminal chain, independently of HCFC1 N-terminal chain. Domain: Although the SET domain contains the active site of enzymatic activity, both sequences upstream and downstream of the SET domain are required for methyltransferase activity. Sequence similarities: Belongs to the histone-lysine methyltransferase family. PR/SET subfamily. Contains 1 SET domain.

SET8 is degraded via PCNA-coupled CRL4(CDT2) ubiquitylation in S phase and after UV irradiation. Jørgensen, S; Eskildsen, M; Fugger, K; Hansen, L; Larsen, MS; Kousholt, AN; Syljuåsen, RG; Trelle, MB; Jensen, ON; Helin, K; Sørensen, CS The Journal of cell biology

The eukaryotic cell cycle is regulated by multiple ubiquitin-mediated events, such as the timely destruction of cyclins and replication licensing factors. The histone H4 methyltransferase SET8 (Pr-Set7) is required for chromosome compaction in mitosis and for maintenance of genome integrity. In this study, we show that SET8 is targeted for degradation during S phase by the CRL4(CDT2) ubiquitin ligase in a proliferating cell nuclear antigen (PCNA)-dependent manner. SET8 degradation requires a conserved degron responsible for its interaction with PCNA and recruitment to chromatin where ubiquitylation occurs. Efficient degradation of SET8 at the onset of S phase is required for the regulation of chromatin compaction status and cell cycle progression. Moreover, the turnover of SET8 is accelerated after ultraviolet irradiation dependent on the CRL4(CDT2) ubiquitin ligase and PCNA. Removal of SET8 supports the modulation of chromatin structure after DNA damage. These results demonstrate a novel regulatory mechanism, linking for the first time the ubiquitin-proteasome system with rapid degradation of a histone methyltransferase to control cell proliferation.
