HIV protein: Nef
Interaction type: binds
Description: HIV-1 Nef-induced downregulation of MHC-I expression and MHC-I targeting to the trans-Golgi network (TGN) require the binding of Nef (amino acid residues 62-65) to PACS-1, a molecule that controls the TGN localization of the cellular protein furin
