A few months ago, research efforts led by Dr. Eran Meshorer (of Alexander Silberman Institute of Life Sciences at the Hebrew University) and Dr. Miguel Ramalho - Santos (of the University of California, San Francisco) published findings that suggest that Chd1 regulates euchromatin in mouse ESCs (Gaspar - Maia et al., 2009).

The goal of this collaboration is to produce a high - quality, publicly available sequence of Drosophila euchromatin by the end of this year. (fruitfly.org)
However, when the histones are not bound to the DNA, the chromatin is extended (called euchromatin), and the DNA can be accessed and these genes can be expressed. (allthingsstemcell.com)
