Overlapping Motifs (PTAP and PPEY) within the Ebola Virus VP40 Protein Function Independently as Late Budding Domains: Involvement of Host Proteins TSG101 and VPS-4

Abstract excerpt

The VP40 protein of Ebola virus can bud from mammalian cells in the form of lipid-bound, virus-like particles (VLPs), and late budding domains (L-domains) are conserved motifs (PTAP, PPxY, or YxxL; where "x" is any amino acid) that facilitate the budding of VP40-containing VLPs. VP40 is unique in that potential overlapping L-domains with the sequences PTAP and PPEY are present at amino acids 7 to 13 of VP40...
