Determination of GP5 domains interact with MYH9 C-terminal region. (A) Predicted topological structure PRRSV SD16 GP5 (top panel) and two ectodomains (Ecto-1 and Ecto-2; bottom panel) and a cytoplasmic domain (Cytodomain) were linked with two GSS linkers and labeled with His-tag to form a truncated GP5 protein (designated GP5Δ-His). (B) The purified GP5Δ-His protein was confirmed with SDS-PAGE and Western blot analysis. (C) Far-Western blot analysis of GP5Δ-PRA interaction. Purified GP5Δ-His (2 μg or 5 μg per lane) and PRA (2 μg, 5 μg, or 10 μg per lane), subjected to SDS-PAGE and transferred to PVDF membrane, were probed with PRA and GP5Δ-His, and then detected with Mab2-5G2 and anti-His mAb, respectively. Recombinant swine hepatitis E virus ORF2 protein (sp239) was used as an irrelevant protein control. (D) Indirect ELISA results of GP5Δ-PRA interaction. Purified GP5Δ-His and PRA protein (200, 400, and 800 ng per well) on the solid-phase of the ELISA plate were incubated with PRA and GP5Δ-His, and following detected with Mab2-5G2 and anti-His mAb, respectively. Data are represented as means ± SD. ∗∗P < 0.01; ∗∗∗P < 0.001.
