In the ISWI article, as it stands on 5/4 2023 seems to be conflating ISWI chromatin remodeling complexes and the ISW1 catalytic subunit.

Article Draft[edit]
Lead[edit]
ISWI (Imitation SWItch) is a protein found in the common fruit fly. is one of the five major DNA chromatin remodeling complex types, or subfamilies, found in most eukaryotic organisms.[1] ISWI remodeling complexes place nucleosomes along segments of DNA at regular intervals. The placement of nucleosomes by ISWI protein complexes typically results in the silencing of the DNA because the nucleosome placement prevents transcription of the DNA. [2] ISWI, like the closely related SWI/SNF subfamily, is an ATP-dependent chromatin remodeler. However, the chromatin remodeling activities of ISWI and SWI/SNF are distinct and mediate the binding of non-overlapping sets of DNA transcription factors. [3]
ISW1 it is the first ATPase subunit which has been isolated in the ISWI chromatin remodeling family in the fruit fly Drosophila. This protein presents high level of similarity to the SWI/SNF chromatin remodeling family in the ATPase domain. Outside the ATPase domain ISWI loses the similarity with the member of the SWI/SNF family, possessing a SANT domain instead of the bromodomain. The protein ISWI can interact with several proteins giving three different chromatin-remodeling complexes in Drosophila melanogaster: NURF (nucleosome remodeling factor), CHRAC (chromatin remodeling and assembly complex) and ACF (ATP-utilising chromatin remodeling and assembly factor).
