A new study has uncovered how an exceptionally scarce protein can orchestrate the assembly of large-scale gene-silencing structures inside cells, and what happens when that process breaks down. The ...
Single-molecule imaging shows that three CBX2 protein molecules can seed Polycomb condensates that silence genes in stem cells. The discovery reveals how rare proteins organize genome regulation and ...
Most of our genome is often written off as “junk DNA”, meaning it doesn’t encode for genes that get made into proteins. This so-called junk consists of accumulated DNA elements like viral DNA that got ...
Example of a tumour obtained by reducing the expression levels of a Polycomb protein. On the left is an example of precursor tissue of the eye during normal development. On the right, a tumour has ...
Changes in histone modifications of genes involved in flowering. (a) The removal of Polycomb complexes by SDG7 protein. (b) Transcription elongation and the deposition of H3K36me3 by SDG8 protein. PRE ...
I didn?t want to give the impression from my last two posts that it?s all RNAi all the time at this year?s Keystone Symposium on Epigenetics and Chromatin Remodeling in Development. Polycomb group ...
A scientific team led by researchers at Trinity College Dublin reports the discovery of new mechanisms involved in establishing cellular identity, a process that ensures the billions of different ...
One of the most fascinating discoveries in biology is that cells have mechanisms for dynamically regulating genetic expression. This ability to promote or restrict the transcription of specific genes ...
Different DNA Structures Nucleate the Folding of Proteins to form specific complexes that modulate the readout of genetic information Self-organization is inherent in the way Nature has engineered ...
