Function	"Chromatin-remodeling protein that binds DNA through histones and regulates gene transcription. May specifically recognize and bind trimethylated 'Lys-27' (H3K27me3) and non-methylated 'Lys-4' of histone H3. Plays a role in the development of the nervous system by activating the expression of genes promoting neuron terminal differentiation. In parallel, it may also positively regulate the trimethylation of histone H3 at 'Lys-27' thereby specifically repressing genes that promote the differentiation into non-neuronal cell lineages. Tumor suppressor, it regulates the expression of genes involved in cell proliferation and differentiation. Downstream activated genes may include CDKN2A that positively regulates the p53/TP53 pathway, which in turn, prevents cell proliferation. In spermatogenesis, it probably regulates histone hyperacetylation and the replacement of histones by transition proteins in chromatin, a crucial step in the condensation of spermatid chromatin and the production of functional spermatozoa"

Mutation	518 518 L->A: Reduced affinity for trimethylated histone H3K27me3 619 619 Y->E: Reduced affinity for trimethylated histone H3K27me3 1390 1390 Q->R: Abolishes methylation by N6AMT1
Disease	"DISEASE: Note=Defects in CHD5 may be a cause of the development of cancers from epithelial, neural and hematopoietic origin CHD5 is one of the missing genes in the del(1p36), a deletion which is extremely common in this type of cancers A decrease of its expression, results in increased susceptibility of cells to Ras-mediated transformation in vitro and in vivo (PubMed:17289567)"
