The beads are called nucleosomes. Each nucleosome is made of DNA wrapped around eight histone proteins that function like a spool and are called a histone octamer. Each histone octamer is composed ...

This enzyme is able to silence specific DNA sections by epigenetically modifying histone proteins that package the DNA. These modifications ensure that the DNA is densely packed as heterochromatin ...

These attendant proteins bind to histones and nucleosomal DNA, and their binding to these molecules is affected by the histone modification state. The modification state helps determine whether ...

Now, Warnecke and colleagues are challenging the idea that these space-saving proteins are not commonplace in bacteria. In a preprint uploaded to bioRxiv this January that has yet to undergo peer ...

Scientists at the University of California, Riverside, have discovered how adult stem cells retain their regenerative power.

Histone modification is regulated by various proteins, including “writers” that add modifications, “erasers” that remove them, and “readers” that recognize modified histone residues and recruit ...

Histone modification is an epigenetic mechanism that enables fine-tuning of gene expression. Mutation or dysregulation of proteins associated with histone | Ebooks ...

Modifying histones can affect transcription by altering the structure of chromatin and by facilitating interactions with accessory proteins that recognize modified histones. Thus, histone ...
