Max is likely not at the Drosophila histone locus

The histone locus body (HLB) is a conserved nuclear body that regulates histone mRNA production in metazoans. While some HLB components are known, there are likely uncharacterized factors that target the histone locus. We identified the Drosophila melanogaster protein Max, which interacts with known HLB member Myc, as an HLB candidate. We mapped Max ChIP-seq and ChIP-nexus datasets, which revealed encouraging signal over the histone gene array. However, we discovered that Max does not colocalize with HLB components on polytene chromosomes. Therefore, we conclude that Max is likely not at the D. melanogaster histone locus.
