A member of the Drosophila Nuclear Export Factor (Nxf) family, Nxf2, forms part of the piRNA-dependent co-transcriptional silencing complex and is essential for transposon repression in fly ovaries.
Genome-wide identification of long non-coding RNAs produced by RNA Polymerase V identifies their role in heterochromatin maintenance on the boundaries of repressed regions.
Silencing of stem cell identity genes during progenitor commitment ensures that intermediate progenitors robustly commit to generate differentiated cell types rather than abnormal stem-cell-like cells during indirect neurogenesis.
The METHYL-CpG-BINDING DOMAIN 7 (MBD7) complex promotes the activation (rather than repression) of transgenes that undergo DNA methylation and it does so without significantly altering their methylation status, placing this complex downstream of DNA methylation.
Heterochromatin formation at transposon loci depends on dimerisation of the effector complex that elicits co-transcriptional silencing and this requirement is fulfilled by co-option of the conserved dimerisation hub protein, Cut-up/LC8.
PCGF6 links sequence specific target recognition by the MAX/MGA transcription factor complex to PRC1 (polycomb repressive complex 1) -dependent transcriptional silencing of germ cell-specific genes in mouse pluripotent stem cells.
A pathway directed by the KRAS oncoprotein leads to aberrant hypermethylation and transcriptional silencing of many genes including tumor suppressors, thereby promoting tumor development.
