New research tool tracks real-time DNA-protein binding in cells

Researchers have developed a new technology that precisely marks where groups of regulatory proteins called transcription factors bind DNA in the nuclei of live cells.

Reporting their data Aug. 6 in the journal Molecular Cell, scientists at Cincinnati Children's Hospital Medical Center say the new technology - called SpDamID - could allow scientists to answer basic questions about tissue development and disease that existing technology cannot address.

"With further development this technology has the potential to give investigators glimpses into biological problems that cannot be answered with existing…
