Characterization of the imitation switch subfamily of ATP-dependent chromatin-remodeling factors in Saccharomyces cerevisiae.

Abstract

We have identified and characterized two Imitation Switch genes in Saccharomyces cerevisiae, ISW1 and ISW2, which are highly related to Drosophila ISWI, encoding the putative ATPase subunit of three ATP-dependent chromatin remodeling factors. Purification of ISW1p reveals a four-subunit complex with nucleosome-stimulated ATPase activity, as well as ATP… (More)
