(Submitter supplied) G9a and GLP lysine methyltransferases form a heterodimeric complex that is responsible for the bulk of cellular mono- and di-methylation on histone H3 lysine 9 (H3K9me1/me2). Widely Interspaced Zinc finger (WIZ) associates with the G9a/GLP protein complex, but its role in lysine methylation is poorly defined. Here, we show that WIZ regulates global H3K9me2 levels through a mechanism that involves retention of G9a on chromatin. more...

(Submitter supplied) Proliferating progenitor cells undergo unidirectional changes in competence to give rise to post-mitotic progeny of specialized function. These transitions in cell fate typically involve the dynamic regulation of gene expression programs by histone methyltransferase (HMT) complexes. However, the composition, roles and regulation of these HMT complexes in regulating cell fate decisions in vivo are poorly understood. more...

(Submitter supplied) G9a/GLP and Polycomb Repressive Complex 2 (PRC2) are two major epigenetic silencing machineries, which in particular methylate histone H3 on lysines 9 and 27 (H3K9 and H3K27), respectively. Although evidence of a crosstalk between H3K9 and H3K27 methylations has started to emerge, their actual interplay remains elusive. Here, we show that PRC2 and G9a/GLP interact physically and functionally. Moreover, combining different genome-wide approaches, we demonstrate that Ezh2 and G9a/GLP share an important number of common genomic targets, encoding developmental and neuronal regulators. more...

(Submitter supplied) We use ChIP-Seq and RNA-Seq technology to profile the H3K9me2 modification and transcription under different conditions of GLP activity. GLP and G9a are major H3K9 dimethylases, and are essential for mouse early embryonic development. Here we report that GLP and G9a possess intrinsic histone methylation propagating activities. The histone methyltransferase activities of GLP and G9a are stimulated by neighboring nucleosomes pre-methylated at H3K9. more...

(Submitter supplied) The euchromatin histone methyltransferase 2 (EHMT2, aka G9a) methylates histone H3K9 to repress gene expression, but it also acts as a coactivator for some nuclear receptors. The molecular mechanisms underlying this activation remain elusive. Here we show that G9a functions as a bona fide coactivator of the endogenous estrogen receptor α (ERα) in breast cancer cells in a histone methylation-independent manner. more...

(Submitter supplied) DNA methylation is an essential epigenetic mark in mammals, and its pattern has to be re-established after each round of DNA replication. The protein UHRF1 is known to be necessary for this process, but its mode of action is unclear. Using proteomics, we havefound that a replication factor, DNA Ligase 1 (LIG1), is a direct interactor of UHRF1. The interaction is mediated bythe Tudor domain of UHRF1 and an H3K9-like histone mimic within LIG1. more...

(Submitter supplied) G9a is a lysine methyltransferase that regulates epigenetic modifications, transcription and genome organization. However, whether these properties are dependent on one another or represent distinct functions of G9a remains unclear. In this study, we observe widespread DNA methylation loss in G9a depleted and catalytic mutant embryonic stem cells. Furthermore, we define how G9a regulates chromatin accessibility, epigenetic modifications and transcriptional silencing in both catalytic dependent and independent manners. more...

(Submitter supplied) Mice heterozygous for a null mutation in Widely-interspaced zinc finger, Wiz, were produced in a screen for modifiers of epigenetic reprogramming; expression of the GFP reporter transgene decreased in mutants, suggesting a role in transcriptional activation (Daxinger et al., 2013). These mice are viable and fertile, with no overt abnormalities and homozygosity for the mutation is embryonic lethal (Daxinger et al, 2013). more...

Analysis of MDA-MB231 breast cancer cells depleted for G9a, a methyltransferase that mediates histone H3 lysine-9 di-methylation (H3K9me2). G9a depletion inhibits migratory ability and invasiveness of MDA-MB231 cells. Results provide insight into role of G9a and H3K9me2 in breast cancer progression.

(Submitter supplied) The role of the histone mehyltrasferase G9a (also known as Ehmt2) in heart has not been extensively studied. To identify the genes regulated by G9a in the normal heart, we first generated a conditional, cardiac-specific KO mouse for this gene using the Cre-Lox approach, crossing G9a flox/flox mice with αMHC-MerCreMer mice (Cre mice were used as controls). Then, we sequenced total RNA (Total-RNA-seq) from cardiomyocyte-enriched populations isolated from G9a-KO and Cre mice, and compared the two expression profiles.

Then we performed ChIP-seq for G9a and H3K9me2 – the main histone methylation catalysed by the HMT – on isolated G9a-KO and Cre CMs, and considered the best G9a-bound genomic regions as those that had a loss or decrease of G9a binding as well as a lower level of H3K9me2 in G9a-KO CMs. more...
