SASDV67 – Human Splicing Factor Proline/Glutamine rich SFPQ1 dimer with C-terminal truncation (delta599-707)
Synchrotron SAXS
data from solutions of
Human Splicing Factor Proline/Glutamine rich SFPQ1 dimer with C-terminal truncation (delta599-707)
in
500mM KNO3, 20mM HEPES, 5% glycerol, 1mM DTT, pH 7.4
were collected
on the
SAXS/WAXS beam line
at the Australian Synchrotron storage ring
(Melbourne, Australia)
using a Pilatus3 S 2M detector
at a sample-detector distance of 3 m and
at a wavelength of λ = 0.10781 nm
(I(s) vs s, where s = 4πsinθ/λ, and 2θ is the scattering angle).
One solute concentration of 5.00 mg/ml was measured
at 25°C.
400 successive
1 second frames were collected.
The data were normalized to the intensity of the transmitted beam and radially averaged; the scattering of the solvent-blank was subtracted.
SFPQ as a dimer truncated to remove the C-terminal Intrinsically Disordered Region (IDR).
Experiment carried out at the SAXS/WAXS beamline with protein at 5mg/ml in 500mM KNO3, 20mM HEPES (pH 7.4), 5% glycerol, 1mM DTT.
This data is part of the manuscript ' Structural dynamics of IDR interactions in human SFPQ and implications for liquid-liquid phase separation '.
