N-terminal; associates with the host plasma membrane
Acidic; stabilizes the interaction of NEF/MHC-I with host AP1M1; necessary for MHC-I internalization and interaction with host PACS1 and PACS2
SH3-binding; interaction with Src family tyrosine kinases
Mediates dimerization, Nef-PTE1 interaction
Binding to ATP6V1H
Necessary for MHC-I internalization
