Complex formation of GRE with ΔBTB-GZF1. (A) ³²P-labeled GRE was incubated with GST-ΔBTB-GZF1 in the absence or presence of anti-GST antibody or normal mouse IgG. The arrow indicates the GRE-GST-ΔBTB-GZF1 complex and the arrowhead indicates the supershifted complex in the presence of anti-GST antibody. (B) EMSA using GFP-full-length GZF1 or GFP-ΔBTB-GZF1 fusion proteins. Extracts from HEK293T cells transfected with empty pEGFP (lane 1), GFP-full-length GZF1 (lane 2) or GFP-ΔBTB-GZF1 (lane 3) plasmid were analyzed for binding with ³²P-labeled GRE. An arrowhead indicates the DNA-GFP-ΔBTB-GZF1 complex (lane 3).
