12044168-5	2002	To allow ion flux across the membrane Vpu would be required to assemble in homooligomers to form functional water-filled pores.	Water	108-113	Vpu	Human immunodeficiency virus 1	38-41	
9708891-2	1998	A pentameric bundle of unconstrained helices (residues 6-28 of Vpu) with a water filled pore was initially assembled in a membrane mimetic octane/water system.	Water	75-80	Vpu	Human immunodeficiency virus 1	63-66	
11259297-3	2001	Langmuir monolayers of mixtures of Vpu and the phospholipid 1,2-dilignoceroyl-sn-glycero-3-phosphocholine (DLgPC) at the water-air interface were studied by synchrotron radiation-based x-ray reflectivity over a range of mole ratios at constant surface pressure and for several surface pressures at a maximal mole ratio of Vpu/DLgPC.	Water	121-126	Vpu	Human immunodeficiency virus 1	35-38	
9708891-2	1998	A pentameric bundle of unconstrained helices (residues 6-28 of Vpu) with a water filled pore was initially assembled in a membrane mimetic octane/water system.	Water	146-151	Vpu	Human immunodeficiency virus 1	63-66	
9108308-2	1997	Models of Vpu channels formed by bundles of N = 4, 5 or 6 transmembrane helices have been developed by restrained molecular dynamics and refined by 100 ps simulations with water molecules within the pore.	Water	172-177	Vpu	Human immunodeficiency virus 1	10-13
