The protein encoded by this gene is a histone methyltransferase that methylates the lysine-9 position of histone H3. This action marks the genomic region packaged with these methylated histones for transcriptional repression. This protein may be involved in the silencing of MYC- and E2F-responsive genes and therefore could play a role in the G0/G1 cell cycle transition. Defects in this gene are a cause of chromosome 9q subtelomeric deletion syndrome (9q-syndrome, also known as Kleefstra syndrome). Alternative splicing results in multiple transcript variants.

GeneCards Summary for EHMT1 Gene
EHMT1 (Euchromatic Histone Lysine Methyltransferase 1) is a Protein Coding gene. Diseases associated with EHMT1 include Kleefstra Syndrome and Autism Spectrum Disorder. Among its related pathways are Chromatin organization and Cellular Senescence (REACTOME). GO annotations related to this gene include methyltransferase activity and histone-lysine N-methyltransferase activity. An important paralog of this gene is EHMT2.
UniProtKB/Swiss-Prot for EHMT1 Gene
Histone methyltransferase that specifically mono- and dimethylates Lys-9 of histone H3 (H3K9me1 and H3K9me2, respectively) in euchromatin. H3K9me represents a specific tag for epigenetic transcriptional repression by recruiting HP1 proteins to methylated histones. Also weakly methylates Lys-27 of histone H3 (H3K27me). Also required for DNA methylation, the histone methyltransferase activity is not required for DNA methylation, suggesting that these 2 activities function independently. Probably targeted to histone H3 by different DNA-binding proteins like E2F6, MGA, MAX and/or DP1. During G0 phase, it probably contributes to silencing of MYC- and E2F-responsive genes, suggesting a role in G0/G1 transition in cell cycle. In addition to the histone methyltransferase activity, also methylates non-histone proteins: mediates dimethylation of Lys-373 of p53/TP53.
Lysine methyltransferases are enyzmes that catalyze the transfer of methyl groups from S-adenosylmethionine (SAM) to the lysine residues on histones, particularly histones H3 and H4. The dysregulation of this methylation is critical in the development of cancer.
