Crystal structure of Alix V domain
Overview
The modular protein Alix is a central node in endosomal-lysosomal trafficking and the budding of human immunodeficiency virus (HIV)-1. The Gag p6 protein of HIV-1 contains a LYPx(n)LxxL motif that is required for Alix-mediated budding and binds a region of Alix spanning residues 360-702. The structure of this fragment of Alix has the shape of the letter 'V' and is termed the V domain. The V domain has a topologically complex arrangement of 11 alpha-helices, with connecting loops that cross three times between the two arms of the V. The conserved residue Phe676 is at the center of a large hydrophobic pocket and is crucial for binding to a peptide model of HIV-1 p6. Overexpression of the V domain inhibits HIV-1 release from cells. This inhibition of release is reversed by mutations that block binding of the Alix V domain to p6.
