The nucleosome untangled

Article Abstract:

Constant additions to the cast of histone marks and the regulatory proteins that make them, remove them or act upon their presence put the number of potential combinations in the astronomical range. Researchers are attacking histones by mutating them and are targeting modifiable lysines in an effort to dissect biological pathways and networks.
