== Function ==
 +
[https://www.uniprot.org/uniprot/PDC6I_HUMAN PDC6I_HUMAN] Class E VPS protein involved in concentration and sorting of cargo proteins of the multivesicular body (MVB) for incorporation into intralumenal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome. Binds to the phospholipid lysobisphosphatidic acid (LBPA) which is abundant in MVBs internal membranes. The MVB pathway appears to require the sequential function of ESCRT-O, -I,-II and -III complexes. The ESCRT machinery also functions in topologically equivalent membrane fission events, such as the terminal stages of cytokinesis and enveloped virus budding (HIV-1 and other lentiviruses). Appears to be an adapter for a subset of ESCRT-III proteins, such as CHMP4, to function at distinct membranes. Required for completion of cytokinesis. Involved in HIV-1 virus budding. Can replace TSG101 it its role of supporting HIV-1 release; this function implies the interaction with CHMP4B. May play a role in the regulation of both apoptosis and cell proliferation.<ref>PMID:14505569</ref> <ref>PMID:14505570</ref> <ref>PMID:14739459</ref> <ref>PMID:17853893</ref> <ref>PMID:17428861</ref> <ref>PMID:17556548</ref>

== Publication Abstract from PubMed ==
 +
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.
