How 'master regulators' of cells make DNA accessible for gene expression
New insight into proteins called “pioneer factors” helps to explain their unusual ability to open up the typically dense genetic material within our cells. This behavior makes the genetic material accessible for proteins involved in important cellular processes, such as DNA replication and repair, gene expression, and the creation of proteins.

How does an aging-associated enzyme access our genetic material?
New research provides insight into how an enzyme that helps regulate aging and other metabolic processes accesses our genetic material to modulate gene expression within the cell. A team led by Penn State researchers have produced images of a sirtuin enzyme bound to a nucleosome — a tightly packed complex of DNA and proteins called histones — showing how the enzyme navigates the nucleosome complex to access both DNA and histone proteins and clarifying how it functions in humans and other animals.

New image of a cancer-related enzyme in action helps explain gene regulation
New images of an enzyme in action as it interacts with the chromosome could provide important insight into how cells — including cancer cells — regulate their genes.
