ATXR5 and ATXR6 are H3K27 monomethyltransferases required for chromatin structure and gene silencing. [PDF]

open access: yes, 2009
Constitutive heterochromatin in Arabidopsis thaliana is marked by repressive chromatin modifications, including DNA methylation, histone H3 dimethylation at Lys9 (H3K9me2) and monomethylation at Lys27 (H3K27me1).

Age-dependent expression of DNMT1 and DNMT3B in PBMCs from a large European population enrolled in the MARK-AGE study [PDF]

open access: yes, 2016
Aging is associated with alterations in the content and patterns of DNA methylation virtually throughout the entire human lifespan. Reasons for these variations are not well understood.

Role of Mammalian DNA Methyltransferases in Development.

open access: yesAnnual Review of Biochemistry, 2019
DNA methylation at the 5-position of cytosine (5mC) plays vital roles in mammalian development. DNA methylation is catalyzed by DNA methyltransferases (DNMTs), and the two DNMT families, DNMT3 and DNMT1, are responsible for methylation establishment and ...

Enhancer of zeste homolog 2 (EZH2) in pediatric soft tissue sarcomas: first implications

open access: yesBMC Medicine, 2011
Soft tissue sarcomas of childhood are a group of heterogeneous tumors thought to be derived from mesenchymal stem cells. Surgical resection is effective only in about 50% of cases and resistance to conventional chemotherapy is often responsible for ...

Functional Crosstalk between Lysine Methyltransferases on Histone Substrates: The Case of G9A/GLP and Polycomb Repressive Complex 2 [PDF]

open access: yes, 2015
Significance: Methylation of histone H3 on lysine 9 and 27 (H3K9 and H3K27) are two epigenetic modifications that have been linked to several crucial biological processes, among which are transcriptional silencing and cell differentiation.

Functional Diversification and Structural Origins of Plant Natural Product Methyltransferases

open access: yesMolecules, 2022
In plants, methylation is a common step in specialized metabolic pathways, leading to a vast diversity of natural products. The methylation of these small molecules is catalyzed by S-adenosyl-l-methionine (SAM)-dependent methyltransferases, which are ...

Structure of the first representative of Pfam family PF04016 (DUF364) reveals enolase and Rossmann-like folds that combine to form a unique active site with a possible role in heavy-metal chelation. [PDF]

open access: yes, 2010
The crystal structure of Dhaf4260 from Desulfitobacterium hafniense DCB-2 was determined by single-wavelength anomalous diffraction (SAD) to a resolution of 2.01 Å using the semi-automated high-throughput pipeline of the Joint Center for Structural ...

Melatonin-Mediated Development of Ovine Cumulus Cells, Perhaps by Regulation of DNA Methylation

open access: yesMolecules, 2018
Cumulus cells of pre-pubertal domestic animals are dysfunctional, perhaps due to age-specific epigenetic events. This study was designed to determine effects of melatonin treatment of donors on methylation modification of pre-pubertal cumulus cells ...
