The mir-BART2 microRNA precursor found in Human herpesvirus 4 ( Epstein–Barr virus) and Cercopithicine herpesvirus 15. mir-BART2 is expressed in all stages of infection but expression is significantly elevated in the lytic stage. In Epstein-Barr virus, mir-BART2 is found in the
intron An intron is any nucleotide sequence within a gene that is not expressed or operative in the final RNA product. The word ''intron'' is derived from the term ''intragenic region'', i.e. a region inside a gene."The notion of the cistron .e., gene. ...
ic regions of the BART (Bam HI-A region rightward transcript) gene whose function is unknown. mir-BART2 is thought to target the virally encoded DNA polymerase BALF5 for degradation. The mature sequence is excised from the 5' arm of the hairpin.
