Bundles consisting of extended transmembrane segments of Vpu from HIV-1: computer simulations and conductance measurements.
Part of the genome of the human immunodeficiency virus type 1 (HIV-1) encodes for a short membrane protein Vpu, which has a length of 81 amino acids. It has two functional roles: (i) to downregulate CD4 and (ii) to support particle release. These roles are attributed to two distinct domains of the peptide, the cytoplasmic and transmembrane (TM) domains, respectively. It has been suggested that the enhanced particle release function is linked to the ion channel activity of Vpu, with a slight p...Expand abstract
