Figure 3. Interaction of EspO1-2 with EspM2.

Figure 3

(A) GST-EspO1-2 binding assays were performed using cell lysates expressing Flag-tagged Map, EspM2, EspM2 or EspG. Proteins that bound to GST-EspO1-2 and GST-alone were analyzed by SDS-PAGE followed by immunoblotting with anti-Flag antibody. (B) To map the EspM2-binding site in EspO1-2, a series of truncated GST-EspO1-2 peptides was used in binding assays with cell lysate expressing Flag-tagged EspM2. (C) Co-localization of RFP-EspO1-2 and GFP-EspM2 in HeLa cells. HeLa cells were transfected with pRFP-EspO1-2, pRFP-EspO1-2 1–60aa or pRFP (red) and pEGFP-EspM2 (green).
