mir-BHRF1-1 microRNA precursor family
|mir-BHRF1-1 microRNA precursor family|
|RNA type||Gene; miRNA|
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. Two other miRNA precursors were found in this reading frame, namely Mir-BHRF1-2 and Mir-BHRF1-3.
BHRF-1-1 miRNA is thought to operate as part of a 'miRNA cluster' with two other microRNAs also found in the Epstein–Barr virus genome. BHRF-1-1 has been shown to be expressed in latency-III infected lymphoblasts.
