DNA cruciforms

Neville R. Kallenbach, Min Zhong

Research output: Contribution to journalArticlepeer-review


Cruciforms represent a novel DNA state with unique physical and biological properties, including the ability to undergo branch migration in appropriate sequence backgrounds. Recent results establish a preferred geometry of immobile cruciforms in Mg2+ solution, the rate of branch migration, and the binding properties of cruciforms for proteins and small molecule ligands. A structure has been determined for three-arm branches with unpaired bases at the branch.
