Functional similarities between HIV-1 Tat and DNA sequence-specific transcriptional activators.

abstract：:Retroviral nucleocapsid (NC) proteins are small Gag-derived products containing one or two zinc finger motifs that mediate genomic RNA packaging into virions. In this study, we addressed the role of the feline immunodeficiency virus (FIV) NC protein in the late stages of virus replication by analyzing the assembly phe...
