(Submitter supplied) The execution of developmental programs of gene expression requires an accurate partitioning of the genome into distinct compartments, with heterochromatin enriched at the nuclear periphery. In C. elegans embryonic cells, the methylation of histone H3 lysine 9 (H3K9me) is critical for peripheral anchoring via the chromodomain protein CEC-4, while alternative, H3K9me-independent pathway(s) function in differentiated tissues. more...

(Submitter supplied) We compared wild type N2 fed L4440 control RNAi to met-1 mutants fed mes-4 RNAi food. Genes tend to be upregulated rather than downregulated in these mutants. Comparison to available ChIPseq datasets indicates that the upregulated genes are heterochromatic and are not enriched for H3K36 methylation, indicating that H3K36me loss derepresses heterochromatin indirectly.

Comparison to available ChIPseq datasets indicates that the upregulated genes are heterochromatic and are not enriched for H3K36 methylation, indicating that MRG-1 loss derepresses heterochromatin indirectly.

(Submitter supplied) Genomic regions preferentially associate with regions of similar transcriptional activity, partitioning genomes into active and inactive compartments within the nucleus. Here we explored mechanisms controlling genome compartment organization in C. elegans and investigated roles for compartments in regulating gene expression. The distal arms of C. elegans chromosomes, which are enriched for heterochromatic histone modifications including H3K9me, interact with each other both in cis and in trans, while interacting less frequently with central regions of chromosomes, leading to genome compartmentalization. more...

(Submitter supplied) The establishment and maintenance of chromatin domains shape the epigenetic memory of a cell, with histone H3 lysine 9 methylation defining repressed heterochromatin. We show that in C. elegans the SET-25 (SUV39/G9a) HMT that catalyzes H3K9me1-3, is able to establish repressed domains de novo. We identify here two distinct pathways that recruit SET-25 to its targets. One requires LIN-61 (L3MBTL2), a conserved protein with 4 MBT domains that recognizes H3K9me2 deposited by the HMT MET-2 (SETDB1). more...

(Submitter supplied) Packaging genomic regions into silenced heterochromatin is critical to maintain organismal viability and tissue identity. Methylation of histone H3 on lysine 9 (H3K9me) marks heterochromatin. Here we show that in addition to catalyzing H3K9me, the C. elegans histone methyltransferase MET-2 (SETDB1-like) has a second non-catalytic function that can itself contribute to gene repression. We find that subnuclear concentrates, or foci, of MET-2 correlate with efficient HMT activity, yet foci composed of catalytic-deficient MET-2 are also able to mediate transcriptional silencing. more...

(Submitter supplied) The segregation of the genome into accessible euchromatin and histone H3 lysine 9 methylated (H3K9me) heterochromatin is essential for the repression of repetitive elements and tissue-specific genes. In C. elegans, the SETDB1 homolog MET-2 catalyzes H3K9me1 and me2. In worms as in vertebrates, the regulation of this crucial enzyme remains enigmatic. Contrary to the localization of overexpressed MET-2, we find endogenous MET-2 to be nuclear throughout development, enriched in perinuclear foci in a cell cycle-dependent manner. more...
