abstract = {HIV-1 Nef is an important pathogenic factor for HIV/AIDS
pathogenesis. Studies have shown that the association of Nef
with the inner leaflet of the plasma membrane and with
endocytic and perinuclear vesicles is essential for most
activities of Nef. Using purified recombinant proteins in
pull-down assays and by co-immunoprecipitation assays we
demonstrate that Nef binds directly and specifically to all
GABARAP family members, but not to LC3 family members. Based
on nuclear magnetic resonance (NMR) experiments we showed
that Nef binds to GABARAP via two surface exposed
hydrophobic pockets. S53 and F62 of GABARAP were identified
as key residues for the interaction with Nef. During
live-cell fluorescence microscopy an accumulation of Nef and
all GABARAP family members in vesicular structures
throughout the cytoplasm and at the plasma membrane was
observed. This plasma membrane accumulation was
significantly reduced after knocking down GABARAP, GABARAPL1
and GABARAPL2 with respective siRNAs. We identified GABARAPs
as the first known direct interaction partners of Nef that
are essential for its plasma membrane localization.},
