abstract = {Subcellular structures containing autophagy-related
proteins of the Atg8 protein family have been investigated
with conventional wide-field fluorescence and single
molecule localisation microscopy. Fusion proteins of GABARAP
and LC3B, respectively, with EYFP were overexpressed in
HEK293 cells. While size distributions of structures
labelled by the two proteins were found to be similar, shape
distributions appeared quite disparate, with EYFP-GABARAP
favouring circular structures and elliptical structures
being dominant for EYFP-LC3B. The latter also featured a
nearly doubled fraction of U-shape structures. The
experimental results point towards highly differential
localisation of the two proteins, which appear to label
structures representing distinct stages or even specific
channels of vesicular trafficking pathways. Our data also
demonstrate that the application of super-resolution
techniques expands the possibilities of fluorescence-based
methods in autophagy studies and in some cases can rectify
conclusions obtained from conventional fluorescence
microscopy with diffraction-limited resolution.},
