摘要: Hepatitis delta virus (HDV) replicates its genome in the nucleus of an infected cell. However, unsolved problem has been identification cytoplasm a putative mRNA for synthesis only virus-coded protein, antigen. We now report characterization 800-base RNA that is cytoplasmic, polyadenylated, and antigenomic should direct translation This was about 500 times less abundant than full-length genomic RNA. mapped predominant 5' terminus also 3' site at which poly(A) added. At point 15 to 20 bases upstream addition sequence AAUAAA, could have used as signal polyadenylation. When infectious cDNA clone whole HDV changed this UUUAAA, no longer it unable These findings provided additional evidence polyadenylated least method expression Apparently processed if were host polymerase II transcript, although did not necessarily indicate transcribed with enzyme.
