Cleavage of p15 protein in vitro by human immunodeficiency virus type 1 protease is RNA dependent

The human immunodeficiency virus (HIV) gag polyprotein is processed by the viral protease to yield the structural proteins of the virus. One of these structural proteins, p15, and its protease cleavage products, p7 and p6, are believed to be responsible for the viral RNA binding which is prerequisite for assembly of infectious virions. To better understand potential interactions between viral RNA, p15, and the HIV protease, we have synthesized...
