Extended Data Fig. 6. RORα binds Id2 and Nfil3 regulatory elements.
(a) Representative ATAC-seq tracks for thymic ETP, DN2, DN3, NKp and ILC2p around the Bcl11b locus. Tracks shown are representative of three independent experiments.
(b) Representative ATAC-seq tracks for thymic ETP, DN2, DN3, NKp and ILC2p and binding profiles of RORα-T2A and GATA-3-T2A in ILC2 in ILC2 purified from lymph nodes of Rora teal/teal, Gata3hCD2TR/+ or wild type mice, and expanded in vitro with IL-7 and IL-33 around the Id2 and Nfil3 locus. Tracks shown are representative of three independent experiments.
(c) A luciferase assay shows the activity (relative to empty vector) of a DNA fragment containing the RORα-binding site from the Id2-associated -143 kb regulatory region, in the presence of increasing concentrations (as indicated) of RORα, GATA-3 or both. Data are representative of three independent experiments; mean ± SEM; two-way ANOVA with Tukey post-hoc test.
