Mir-BHRF1-1 microRNA precursor family

The mir-BHRF1-1 microRNA precursor found in Human herpesvirus 4 (Epstein-Barr virus) and Cercopithicine herpesvirus 15. In Epstein-Barr virus, mir-BHRF1-1 is found in the 5' 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 5' arm of the hairpin.
