Figure 2 SAXS analysis of SFPQ containing IDRs in high-salt conditions. (a) Domain map indicating protein variants that have been analysed via SAXS. An asterisk denotes previously published data or data in the supporting information on variants of SFPQ or NONO. (b, c) SEC-SAXS scattering for full-length SFPQ and SFPQ1–598, respectively. (d, e) Guinier analysis for full-length SFPQ and SFPQ1–598, respectively; below, the normalized residuals plots of the Guinier fits. (f) Distance distribution functions calculated for all protein variants examined in this study. Functions have been normalized by % P(r) and error bars have been omitted for simplicity (but can be seen later in the study). (g) Dimensionless Kratky plot for all variants used in this study; variants are coloured according to the legend in (f). |
