GO: Interacting selectively and non-covalently with a primary microRNA (pri-miRNA) transcript, an RNA molecule that is processed into a short hairpin-shaped structure called a pre-miRNA and finally into a functional miRNA. Both double-stranded and single-stranded regions of a pri-miRNA are required for binding. [GOC:sl, PMID:15531877, PMID:15574589]
