NUCLEOSOME RECOGNITION MODULE OF ISWI ATPASE
Overview
Energy-dependent nucleosome remodeling emerges as a key process endowing, chromatin with dynamic properties. However, the principles by which, remodeling ATPases interact with their nucleosome substrate to alter, histone-DNA interactions are only poorly understood. We have identified a, substrate recognition domain in the C-terminal half of the remodeling, ATPase ISWI and determined its structure by X-ray crystallography. The, structure comprises three domains, a four-helix domain with a novel fold, and two alpha-helical domains related to the modules of c-Myb, SANT and, SLIDE, which are linked by a long helix. An integrated structural and, functional analysis of these domains provides insight into how ISWI, interacts with the nucleosomal substrate.
