abstract = {Obtaining structural information on integral or peripheral
membrane proteins is currently arduous due to the difficulty
of their solubilization, purification, and crystallization
(for X-ray crystallography (XRC) application). To overcome
this challenge, bicelles are known to be a versatile tool
for high-resolution structure determination, especially when
using solution and/or solid state nuclear magnetic resonance
(NMR) and, to a lesser extent, XRC. For proteins not
compatible with these high-resolution methods, small-angle
X-ray and neutron scattering (SAXS and SANS, respectively)
are powerful alternatives to obtain structural information
directly in solution. In particular, the SANS-based approach
is a unique technique to obtain low-resolution structures of
proteins in interactions with partners by contrast-matching
the signal coming from the latter. In the present study,
isotropic bicelles are used as a membrane mimic model for
SANS-based structural studies of bound peripheral membrane
proteins. We emphasize that the SANS signal coming from the
deuterated isotropic bicelles can be contrast-matched in
$100\%$ D2O-based buffer, allowing us to separately and
specifically focus on the signal coming from the protein in
interaction with membrane lipids. We applied this method to
the DYS-R11–15 protein, a fragment of the central domain
of human dystrophin known to interact with lipids, and we
were able to recover the signal from the protein alone. This
approach gives rise to new perspectives to determine the
solution structure of peripheral membrane proteins
interacting with lipid membranes and might be extended to
integral membrane proteins.},
