Summary: In Drosophila. the piRNAs that guide germline transposon silencing are produced from heterochromatic clusters marked by the HP1 homolog Rhino. We show that Rhino promotes cluster transcript association with UAP56 and the THO complex. forming RNA-protein assemblies that are unique to piRNA precursors. https://lockdownsecuritycanada.shop/product-category/a2b-ford-pre-amp/
