ZapD interacts with FtsZ and with itself in a protein interaction platform yeast assay. (A) Yeast cells expressing GFP-ZapD showed diffusely localized fluorescence at 3 to 4 h postinduction of fusion protein; (B) coexpression of both GFP-ZapD and μNS-FtsZ fusion proteins displayed fluorescent foci; (C) coexpression of GFP-ZapD and μNS-ZapD fusions also displayed focal interactions; (D) yeast cells coexpressing FtsZ fused to GFP and ZapD fused to μNS also displayed fluorescent focal platforms.
