DNA-binding helicase that specifically binds to the promoter of target genes, leading to chromatin remodeling, possibly by promoting deposition of histone H3.3. Involved in myogenesis via interaction with MYOD1: binds to myogenic gene regulatory sequences and mediates incorporation of histone H3.3 prior to the onset of myogenic gene expression, promoting their expression. ATP + H2O = ADP + H(+) + phosphate Interacts with MYOD1. Interacts with histone H3.3. Binds to myogenic gene promoters. Widely expressed. Growth delay late in embryogenesis and perinatal lethality (PubMed:16810678). Heterozygous mice show decreased neonatal viability. Heterozygous mice display glomerulopathy, proteinuria and impaired kidney function. Glomerulopathy may be associated with anemia (PubMed:19142019). Heterozygous mutant also show increased extramedullary hematopoiesis and susceptibility to lymphomas, with defects in hematopoietic stem cell differentiation (PubMed:19137022).
