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 '.
