is an ATP-dependent helicase and a central component of the HDAC-containing nucleosome remodeling and histone deacetylase (NuRD) transcriptional complex. Interacts with MTA1/2, HDAC1, and RbAp46 in the NuRD complex. CHD-4 belongs to the SNF2/RAD54 helicase family of proteins. The NuRD complex, whose subunit composition varies by cell type and in response to physiologic signals, plays central roles in many processes including oncogenesis and metastasis, B cell differentiation, invasive growth of breast cancer, and maintaining the balance between the undifferentiated state and the process of differentiation in embryonic stem cells.
