Chromatin-binding ATPase that regulates histone gene expression; only bromodomain-containing AAA-ATPase in yeast; bromodomain interacts with N-terminal tail of histone H3; relocalizes to cytosol in response to hypoxia; human ortholog ANCCA is coactivator of both estrogen and androgen receptors, and increased expression of ANCCA is associated with breast and prostate cancers with poor prognoses
