piRNA cluster binding piRNA uni-strand cluster binding bhm Binding to uni-strand piRNA clusters, double-stranded DNA regions that give rise to PIWI-interacting RNAs (piRNAs) that map predominantly to only one strand and exhibit hallmarks of canonical Pol II transcription. Uni-strand piRNA clusters are found in many taxa. GO:1990471 molecular_function 2014-08-29T14:37:35Z
