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 ...
The fusion oncoprotein subunit, SS18-SSX, appears to break the guidance system of SWI/SNF (BAF), targeting it aberrantly on chromatin and activating genes that support cancer development. [8] In lab-based experiments, Kadoch showed that it was possible to use healthy subunits to repair the complex and kill the cancerous cells.
There are four subfamilies of chromatin remodelers: SWI/SNF, INO80, ISW1, and CHD. [2] The RSC complex is a 15-subunit chromatin remodeling complex initially found in Saccharomyces cerevisiae, and is homologous to the SWI/SNF complex found in humans. [1] The RSC complex has ATPase activity in the presence of DNA. [1]

Chromatin remodelers in the INO80 subfamily are made of multiple subunit complexes with split ATPase domains. [3] The INO80 subfamily's protein domains are an N-terminus, two RuvB-like proteins (Rvb1 and Rvb2), and a C-terminus. [1] The ATPase domain of the N-terminus functions in the identification of DNA damage and aids in the stability of ...
The NuRD complex contains seven subunits: the histone deacetylase core proteins HDAC1 and HDAC2, the histone-binding proteins RbAp46 and RbAp48, the metastasis-associated proteins MTA1 (or MTA2 / MTA3), the methyl-CpG-binding domain protein MBD3 (or MBD2) and the chromodomain-helicase-DNA-binding protein CHD3 (aka Mi-2alpha) or CHD4 (aka Mi-2beta).
Remodeling proteins work in three distinct ways: they can slide the DNA along the surface of the octamer, replace the one histone dimer with a variant, or remove the histone octamer entirely. No matter the method, in order to modify the nucleosomes, the remodeling complexes require energy from ATP hydrolysis to drive their actions.
