Genomic distribution of CHD7 on chromatin tracks H3K4 methylation patterns.

ABSTRACT: CHD7 is a member of the chromodomain helicase DNA binding domain family of ATP-dependent chromatin remodeling enzymes. De novo mutation of the CHD7 gene is a major cause of CHARGE syndrome, a genetic disease characterized by a complex constellation of birth defects (Coloboma of the eye, Heart defects, Atresia of the choanae, severe Retardation of growth and development, Genital abnormalities, and Ear abnormalities). To gain insight into the function of CHD7, we mapped the distribution of the CHD7 protein on chromatin using the approach of chromatin immunoprecipitation on tiled microarrays (ChIP-chip). These studies were performed in human colorectal carcinoma cells, human neuroblastoma cells, and mouse embryonic stem (ES) cells before and after differentiation into neural precursor cells.
