The binding of the LYPxL motif of late HIV p6Gag and EIAV p9Gag to this domain is necessary for viral budding.This domain is generally central between an N-terminal Bro1 domain, Pfam:PF03097 and a C-terminal proline-rich domain. The retroviruses thus used this domain to hijack the ESCRT system of the cell.	Domain
