Mechanisms for ATP-dependend chromatin remodelling

During the past year, major advances have been made towards understanding the function of ATP-dependent chromatin-remodelling activities both in vitro and in vivo. These suggest that ATP-dependent chromatin-remodelling activities are capable of both altering the structure of individual nucleosomes and acting in concert with other forms of chromatin-modifying enzymes, to regulate the formation and decondensation of chromatin fibres.
