abstract = {The γ-aminobutyric acid type A receptor-associated protein
(GABARAP) and its close paralogs GABARAPL1 and GABARAPL2
constitute a subfamily of the autophagy-related 8 (Atg8)
protein family. Being associated with a variety of dynamic
membranous structures of autophagic and non-autophagic
origin, Atg8 proteins functionalize membranes by either
serving as docking sites for other proteins or by acting as
membrane tethers or adhesion factors. In this study, we
describe that deficiency for GABARAP alone, but not for its
close paralogs, is sufficient for accelerated EGF receptor
(EGFR) degradation in response to EGF, which is accompanied
by the downregulation of EGFR-mediated MAPK signaling,
altered target gene expression, EGF uptake, and EGF vesicle
composition over time. We further show that GABARAP and EGFR
converge in the same distinct compartments at endogenous
GABARAP expression levels in response to EGF stimulation.
Furthermore, GABARAP associates with EGFR in living cells
and binds to synthetic peptides that are derived from the
EGFR cytoplasmic tail in vitro. Thus, our data strongly
indicate a unique and novel role for GABARAP during EGFR
trafficking.},
