Probable ATP-dependent chromatin-remodeling factor. Acts as a transcriptional coactivator for PPARA and possibly other nuclear receptors. Has DNA-dependent ATPase activity and binds to A/T-rich DNA. Associates with A/T-rich regulatory regions in promoters of genes that participate in the differentiation of progenitors during osteogenesis (By similarity). {ECO:0000250, ECO:0000269|PubMed:16095617, ECO:0000269|PubMed:16554032}. This is the function of Ensembl gene identifier ENSG00000177200 (CHD9, chromodomain helicase DNA binding protein 9).
