Knockdown of actin-related subunit, BAP55, reduces Su(H) recruitment in both Notch-OFF (PBS treatment) and Notch-ON (EGTA treatment) conditions. Fold enrichment of Su(H) occupancy at the indicated positions detected by ChIP, relative to input, in Kc167 cells treated with Bap55 or lacZ RNAi as a control. Mean +/- SEM; n = 3; * p<0.05 with one-tailed student's t-test compared to lacZ RNAi control.
