Vip (Virulence protein), like the LPXTG-type internalins, is an LPXTG-anchored surface protein of the mammalian cell-invading pathogen Listeria monocytogenes, but absent from the related species Listeria innocua. For certain cell types, Vip is required for Listeria's ability to invade. It appears to bind the endoplasmic reticulum (ER) resident chaperone Gp96 as its receptor.
