The role of Gag in human immunodeficiency virus type 1 virion morphogenesis and early steps of the viral life cycle.

abstract：:The retroviral primary transcription product is a multifunctional RNA that is utilized as pre-mRNA, mRNA, and genomic RNA. The relationship between human immunodeficiency virus type 1 (HIV-1) unspliced transcripts used as mRNA for viral protein synthesis and as virion precursor RNA (vpRNA) for encapsidation remains an...
