The CHD family of enzymes play crucial roles in regulating chromatin dynamics, cell fate, identity, and embryonic development, and may serve as valuable targets for therapeutic intervention."
Chromatin is highly dynamic, undergoing continuous global changes in its structure and type of histone and DNA modifications governed by processes such as transcription, repair, replication, and recombination. Members of the chromodomain helicase DNA-binding (CHD) family of enzymes are ATP-dependent chromatin remodelers that are intimately involved in the regulation of chromatin dynamics, altering nucleosomal structure and DNA accessibility. Genetic studies in yeast, fruit flies, zebrafish, and mice underscore essential roles of CHD enzymes in regulating cellular fate and identity, as well as proper embryonic development. With the advent of next-generation sequencing, evidence is emerging that these enzymes are subjected to frequent DNA copy number alterations or mutations and show aberrant expression in malignancies and other human diseases. As such, they might prove to be valuable biomarkers or targets for therapeutic intervention. In this review, Alendar and Berns discuss emerging evidence that the chromodomain helicase DNA-binding (CHD) family of enzymes is subjected to frequent DNA copy number alterations or mutations and shows aberrant expression in malignancies and other human diseases.
