Acts as a transcriptional coactivator for PPARA and possibly other nuclear receptors. Proposed to be a ATP-dependent chromatin remodeling protein. Has DNA-dependent ATPase activity and binds to A/T-rich DNA (By similarity). Associates with A/T-rich regulatory regions in promoters of genes that participate in the differentiation of progenitors during osteogenesis. ATP + H2O = ADP + H(+) + phosphate Interacts with PPARA. Probably interacts with ESR1 and NR1I3 (By similarity). Expressed in osteoprogenitor cells during development and in mature bone (at protein level). Expressed from embryonic day 16.5 dpc in mesenchymal cartilage surrounding bone cartilage and newly formed bone trabecular spicules. Detected in bone sections of 4-day-old newborn and 3-week-old mice. Phosphorylated on serine and tyrosine residues. Belongs to the SNF2/RAD54 helicase family.
