Human immunodeficiency virus vpr product is a virion-associated regulatory protein

E A Cohen et al. J Virol. 1990 Jun.

Abstract

The vpr product of the human immunodeficiency virus type 1 (HIV-1) acts in trans to accelerate virus replication and cytopathic effect in T cells. Here it is shown that the HIV-1 viral particle contains multiple copies of the vpr protein. The vpr product is the first regulatory protein of HIV-1 to be found in the virus particle. This observation raises the possibility that vpr acts to facilitate the early steps of infection before de novo viral protein synthesis occurs.
