Suppressor of variegation 3-9 homolog 1

SUV39H1, Suv39h
This gene is a member of the suppressor of variegation 3-9 homolog family and encodes a protein with a chromodomain and a C-terminal SET domain. This nuclear protein moves to the centromeres during mitosis and functions as a histone methyltransferase, methylating Lys-9 of histone H3. Overall, it plays a vital role in heterochromatin organization, chromosome segregation, and mitotic progression. [provided by RefSeq, Jul 2008] (from NCBI)

Stem Cell Depletion by Global Disorganization of the H3K9me3 Epigenetic Marker in Aging.
Larrick et al., Sunnyvale, United States. In Rejuvenation Res, Aug 2015
Although WRN plays a role in DNA repair, WRN exerted its effects on aging via maintaining heterochromatin, evidenced by reduced levels of interacting chromatin regulators heterochromatin protein 1α (HP1α), suppressor of variegation 3-9 homolog 1 (SUV39H1), and lamina-associated polypeptide 2β (LAP2β) as well as modified histone H3K9me3.

Moazed et al., Boston, United States. In Science, May 2015
The putative JmjC domain H3K9 demethylase, Epe1, and the chromodomain of the H3K9 methyltransferase, Clr4/Suv39h, play opposing roles in maintaining silent H3K9me domains.
DOT1L inhibits SIRT1-mediated epigenetic silencing to maintain leukemic gene expression in MLL-rearranged leukemia.
Armstrong et al., New York City, United States. In Nat Med, Apr 2015
DOT1L inhibits chromatin localization of a repressive complex composed of SIRT1 and the H3K9 methyltransferase SUV39H1, thereby maintaining an open chromatin state with elevated H3K9 acetylation and minimal H3K9 methylation at MLL fusion target genes.

Thakker, Oxford, United Kingdom. In Mol Cell Endocrinol, 2014
Thus, menin by forming a subunit of the mixed lineage leukemia (MLL) complexes that trimethylate histone H3 at lysine 4 (H3K4), facilitates activation of transcriptional activity in target genes such as cyclin-dependent kinase (CDK) inhibitors; and by interacting with the suppressor of variegation 3-9 homolog family protein (SUV39H1) to mediate H3K methylation, thereby silencing transcriptional activity of target genes.
Epigenetic regulation of EMT: the Snail story.
Zhou et al., Lexington, United States. In Curr Pharm Des, 2013
