Knockdown of components of the BRM complex reduces Su(H) recruitment both in Notch-OFF (B) and Notch-ON (C) conditions. Fold enrichment of Su(H) occupancy at the indicated positions detected by ChIP, relative to input, in Kc167 cells treated with brm, Snr1 or GFP RNAi as a control. Notch-ON conditions (C) were induced by 30 minutes of EGTA treatment. Mean +/- SEM, n = 3 (B); Mean, n = 2 (C); * p<0.05 with one-tailed student's t-test compared to GFP RNAi control.
