A naturally occurring variation in the proline-rich region does not attenuate human immunodeficiency virus type 1 nef function

J Virol. 2004 Sep;78(18):10197-201. doi: 10.1128/JVI.78.18.10197-10201.2004.

Abstract

We analyzed human immunodeficiency virus type 1 (HIV-1) Nef variants to further evaluate the functional relevance of the R71T substitution previously proposed to attenuate viral replication (Fackler et al., Curr. Biol. 11:1294-1299, 2001). Our results demonstrate that this variation in the proline-rich region does not significantly affect the functional activity of Nef or HIV-1 infectivity or replication.
