The BAR domain is the eponymous domain of the "BAR-domain protein superfamily", a
large and diverse set of mostly multi-domain proteins that play eminent roles at
the membrane cytoskeleton interface. BAR domain homodimers are the functional
units that peripherally associate with lipid membranes and are involved in
membrane sculpting activities. Differences in their intrinsic curvatures and
lipid-binding properties account for a large variety in membrane modulating
properties. Membrane activities of BAR domains are further modified and regulated
by intramolecular or inter-subunit domains, by intermolecular protein
interactions, and by posttranslational modifications. Rather than providing
detailed cell biological information on single members of this superfamily, this
review focuses on biochemical, biophysical, and structural aspects and on recent
findings that paradigmatically promote our understanding of processes driven and
modulated by BAR domains.
