Chromatin-remodeling complex ATPase chain Iswi

Gene

Iswi

Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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). 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.4 Publications
