Histone lysine demethylases function as co-repressors of SWI/SNF remodeling activities during Drosophila wing development

► Brahma complex regulates Egfr, Notch, DPP and Wg signaling in the wing. ► Histone lysine demethylases interact with the Brm complex. ► LSD1 demethylase functions as a corepressor of Brm/PBAP complex targets. ► Jumonji domain proteins regulate wing pattern pathways. ► LSD1 demethylase represses wing vein development in intervein cells.
