Heterochromatin: proteins in flux lead to stable repression.
Heterochromatin is a phenotypically stable entity, but recent studies on the binding of HP1 protein in heterochromatin indicate that the individual components within these domains are not stably bound but in constant flux. These results force us to reexamine previous models of heterochromatin.
