Function

ISWI_DROME Energy-transducing component of the chromatin-remodeling complexes NURF (nucleosome-remodeling factor), ACF (ATP-utilizing chromatin assembly and remodeling factor), and CHRAC (chromatin accessibility complex) (PubMed:10856248, PubMed:11447119). NURF catalyzes ATP-dependent nucleosome sliding and facilitates transcription of chromatin. It is required for homeotic gene expression, proper larval blood cell development, normal male X chromosome morphology, ecdysteroid signaling and metamorphosis (PubMed:12502740, PubMed:16264191, PubMed:8521501, PubMed:8521502).^[1] ^[2] ^[3] ^[4] ^[5] ^[6]

Publication Abstract from PubMed

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.
