WebCHD1 is named for three of its protein domains: two tandem chromodomains, its ATPase catalytic domain, and its DNA-binding domain (Figure 1). [8] [9] The CHD1 remodeler binds nucleosomes and induces local changes in nucleosome positioning through ATP hydrolysis coupled to DNA translocation of the DNA across the histone proteins. [8] WebCHD1 is a tumor suppressor and plays a significant role in the development of prostate cancer. CHD1 is located at 5q21, and deletions within this region are one of the most frequent to occur in prostate cancer, second only to PTEN.
