MadID, a Versatile Approach to Map Protein-DNA Interactions, Highlights Telomere-Nuclear Envelope Contact Sites in Human Cells

open access: yesCell Reports, 2018
Summary: Mapping the binding sites of DNA- or chromatin-interacting proteins is essential to understanding biological processes. DNA adenine methyltransferase identification (DamID) has emerged as a comprehensive method to map genome-wide occupancy of ...

On the evolutionary origin of eukaryotic DNA methyltransferases and Dnmt2.

open access: yesPLoS ONE, 2011
The Dnmt2 enzymes show strong amino acid sequence similarity with eukaryotic and prokaryotic DNA-(cytosine C5)-methyltransferases. Yet, Dnmt2 enzymes from several species were shown to methylate tRNA-Asp and had been proposed that eukaryotic DNA ...

DNA Methyltransferases, DNA Damage Repair, and Cancer [PDF]

open access: yes, 2012
The maintenance DNA methyltransferase (DNMT) 1 and the de novo methyltransferases DNMT3A and DNMT3B are all essential for mammalian development. DNA methylation, catalyzed by the DNMTs, plays an important role in maintaining genome stability. Aberrant expression of DNMTs and disruption of DNA methylation patterns are closely associated with many forms ...

Recurrent acral ulcerations associated with DNA methyltransferase 1-complex disorder

open access: yesRevista da Sociedade Portuguesa de Dermatologia e Venereologia, 2022
DNA methyltransferase 1, encoded by DNMT gene, is a crucial DNA methyltransferase with essential roles in transcription regulation, gene imprinting, and cell differentiation.

MamA essentiality in Mycobacterium smegmatis is explained by the presence of an apparent cognate restriction endonuclease

open access: yesBMC Research Notes, 2020
Objective Restriction-Modification (R-M) systems are ubiquitous in bacteria and were considered for years as rudimentary immune systems that protect bacterial cells from foreign DNA.

Trithorax group proteins: switching genes on and keeping them active [PDF]

open access: yes, 2011
Cellular memory is provided by two counteracting groups of chromatin proteins termed Trithorax group (TrxG) and Polycomb group (PcG) proteins. TrxG proteins activate transcription and are perhaps best known because of the involvement of the TrxG protein ...

Flexibility of the linker between the domains of DNA methyltransferase SsoII revealed by small-angle X-ray scattering: implications for transcription regulation in SsoII restriction-modification system.

open access: yesPLoS ONE, 2014
(Cytosine-5)-DNA methyltransferase SsoII (M.SsoII) consists of a methyltransferase domain (residues 72-379) and an N-terminal region (residues 1-71) which regulates transcription in SsoII restriction-modification system.

Aberrant DNA and RNA Methylation Occur in Spinal Cord and Skeletal Muscle of Human SOD1 Mouse Models of ALS and in Human ALS: Targeting DNA Methylation Is Therapeutic

open access: yesCells, 2022
Amyotrophic lateral sclerosis (ALS) is a fatal disease. Skeletal muscles and motor neurons (MNs) degenerate. ALS is a complex disease involving many genes in multiple tissues, the environment, cellular metabolism, and lifestyles.

Methylation is maintained specifically at imprinting control regions but not other DMRs associated with imprinted genes in mice bearing a mutation in the Dnmt1 intrinsically disordered domain

open access: yesFrontiers in Cell and Developmental Biology, 2023
Differential methylation of imprinting control regions in mammals is essential for distinguishing the parental alleles from each other and regulating their expression accordingly.

Expression in mammalian cells of a cloned gene encoding murine DNA methyltransferase [PDF]

open access: yes, 1991
Mammalian DNA cytosine-5-methyltransferase (MTase, EC 2.1.1.37) is an essential component for establishing and maintaining cell-type specific methylation patterns in the genome. The cDNAfor the murine enzyme was previously cloned in segments.
