Lysine Methyltransferase 5A (KMT5A) is an enzyme which catalyzes both histones and non-histone proteins. KMT5A contributes to the maintenance of proper higher-order structure of DNA during mitosis. KMT5A takes part in cell-cycle-dependent transcriptional silencing and mitotic regulation in metazoans. KMT5A plays a role as a barrier to prevent cellular senescence through chromatinmediated regulation of senescence-associated metabolic remodeling. KMT5A mediates monomethylation of p53/TP53 at 'Lys-382', which leads to repress p53/TP53-target genes. The loss of KMT5A simultaneously stimulate nucleolar function and retinoblastoma protein-mediated mitochondrial metabolism.
KMT5A produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 165 amino acids (195-352 a.a.) and having a molecular mass of 18.9kDa (Migrates at 18-28 kDa on SDS-PAGE under reducing conditions).KMT5A is expressed with a 7 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
UniProt Protein Function: | SETD8: a protein-lysine N-methyltransferase that monomethylates both histones and non-histone proteins. Methylates K20 of histone H4 (H4K20me1), a specific tag for epigenetic transcriptional repression. SETD8 protein and H4K20me1 levels are cell cycle regulated, both increasing in S phase and peaking at G2/M phase. Interacts with the PCNA protein, associates with sites of active DNA synthesis and is required for DNA replication and genome stability during S phase. Inhibition of SET8 using shRNA results in arrest of replication forks, induction of double-stranded DNA breaks and a Chk1-mediated cell-cycle arrest in S and G2/M phases of the cell cycle. 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. Inhibition of SET8 using shRNA results in arrest of replication forks, induction of double-stranded DNA breaks and a Chk1-mediated cell-cycle arrest in S and G2/M phases of the cell cycle. Nucleosomes are preferred as substrate compared to free histones. Methylates p53K382, leading to repression of the pro-apoptotic and checkpoint activation functions of p53. SET8 expression levels decrease in response to DNA damage, allowing p53 to activate checkpoints and/or apoptosis. Both the methylation of histone H4K20 and p53K382 appear to be important for the functions of SET8 in S phase. Belongs to the histone-lysine methyltransferase family. PR/SET subfamily. Two isoforms of the human protein are produced by alternative splicing. |
