Such remodeling is principally carried out by 1) covalent histone modifications by specific enzymes, e.g., histone acetyltransferases (HATs), deacetylases, methyltransferases, and kinases, and 2) ATP-dependent chromatin remodeling complexes which either move, eject or restructure nucleosomes. [1]
In molecular biology, SWI/SNF (SWItch/Sucrose Non-Fermentable), [1] [2] is a subfamily of ATP-dependent chromatin remodeling complexes, which is found in eukaryotes.In other words, it is a group of proteins that associate to remodel the way DNA is packaged.
Chromodomain helicase DNA-binding (CHD) proteins is a subfamily of ATP-dependent chromatin remodeling complexes (remodelers). All remodelers fall under the umbrella of RNA/DNA helicase superfamily 2. In yeast, CHD complexes are primarily responsible for nucleosome assembly and organization. These complexes play an additional role in ...
RSC (Remodeling the Structure of Chromatin) is a member of the ATP-dependent chromatin remodeler family. The activity of the RSC complex allows for chromatin to be remodeled by altering the structure of the nucleosome. [1] There are four subfamilies of chromatin remodelers: SWI/SNF, INO80, ISW1, and CHD. [2]

In the field of molecular biology, the Mi-2/NuRD (Nucleosome Remodeling Deacetylase) complex, is a group of associated proteins with both ATP-dependent chromatin remodeling and histone deacetylase activities.
Nucleosome Remodeling Factor (NURF) is an ATP-dependent chromatin remodeling complex first discovered in Drosophila melanogaster (fruit fly) that catalyzes nucleosome sliding in order to regulate gene transcription. It contains an ISWI ATPase, making it part of the ISWI family of chromatin remodeling complexes. NURF is highly conserved among ...
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 ...
