Characterization of Human Cytomegalovirus (HCMV) Long Non-Coding RNA1.2 During Lytic Replication.

ABSTRACT: During lytic replication of human cytomegalovirus (HCMV), the most abundant viral transcripts are long non-coding RNAs (lncRNAs). Viral lncRNAs can have a variety of functions, some of which are necessary for viral production and the modulation of host processes during infection. HCMV produces four lncRNAs, Beta2.7 (RNA2.7), RNA4.9, RNA5.0 and RNA1.2. While there has been research on these viral lncRNAs, many of their functions remain uncharacterized. To determine the function of RNA1.2, we explored its requirement during lytic infection by generating viral mutants containing either a full or partial deletion of the RNA1.2 locus. Within permissive fibroblasts, the RNA1.2 deletion mutants showed no defects in viral DNA synthesis, transcript expression, protein production, or generation of v
