Mir-BHRF1-2 microRNA precursor family

The mir-BHRF1-2 microRNA precursor found in human herpesvirus 4 (Epstein-Barr virus), cercopithicine herpesvirus 15 and herpesvirus papio. In Epstein-Barr virus, mir-BHRF1-2 is found in the 3' UTR of the BHRF1 (Bam HI fragment H rightward open reading frame 1) gene, which is known to encode a distant Bcl-2 homolog. The mature sequence is excised from the 3' arm of the hairpin.
