23613843-2	2013	In the present study, we found that the loss of virus infectivity as a result of envelope (Env) incorporation defect caused by a Gag matrix (MA) mutation (L30E) was significantly alleviated by introducing a start codon mutation in vpu.

9338017-2	1997	Interestingly, Vpu was also shown to enhance the release of capsids produced by gag gene contructs of other retroviruses that lack a Vpu-like activity.	Glycosaminoglycans	80-83	Vpu	Human immunodeficiency virus 1	15-18
