Major advances in understanding the regulation and organization of the human genome
Date:9/5/2012

The National Human Genome Research Institute today announced the results of a five-year international study of the regulation and organization of the human genome. The project is named ENCODE, which stands for the Encyclopedia of DNA Elements. In conjunction with the release of those results, the Journal of Biological Chemistry has published a series of reviews that focus on several aspects of the findings.

"The ENCODE project not only generated an enormous body of data about our genome, but it also analyzed many issues to better understand how the genome functions in different types of cells. These insights from integrative analyses are really stories about how molecular machines interact with each other and work on DNA to produce the proteins and RNAs needed for each cell to function within our bodies," explains Ross Hardison of Pennsylvania State University, one of the JBC authors.

Hardison continued: "The Journal of Biological Chemistry recognized that the results from the ENCODE project also would catalyze much new research from biochemists and molecular biologists around the world. Hence, the journal commissioned these articles not only to communicate the insights from the papers now being published but also to stimulate more research in the broader community."

The human genome consists of about 3 billion DNA base pairs, but only a small percentage of DNA actually codes for proteins. The roles and functions of the remaining genetic information were unclear to scientists and even referred to as "junk DNA." But the results of the ENCODE project is filling this knowledge gap. The findings revealed that more than 80 percent of the human genome is associated with biological function.

The study showed in a comprehensive way that proteins switch genes on and off regularly and can do so at distances far from the genes they regulate and it determined sites on chromosomes that interact, the locations where chemic
