Figure Lengend Snippet: ENO1 interacts with the NP protein. ( A , B ) HEK293T cells were transfected individually or in combination with Flag-tagged ENO1 and HA-tagged NP. At 24 h post-transfection, lysates of cells were immunoprecipitated with mouse anti-Flag mAb (A) or mouse anti-HA mAb (B) and then western blotted with rabbit anti-Flag pAb and rabbit anti-HA pAb, respectively. ( C ) HEK293T cells were infected with H1N1 virus (MOI = 5). At 12 h p.i., lysates from HEK293T cells were immunoprecipitated with mouse anti-ENO1 pAb, followed by western blotting with rabbit anti-ENO1 pAb and rabbit anti-NP pAb, respectively. ( D ) Purified GST and GST-ENO1 protein were used to pull down Flag-tagged NP. ( E ) A549 cells were uninfected or infected with H1N1 virus (MOI = 5). At 12 h p.i., the cells were fixed and stained with mouse anti-NP mAb and rabbit anti-ENO1 pAb. Scale bars, 5 μm. ( F , G ) HEK293T cells were transfected with the indicated plasmids. At 24 h post-transfection, cell lysates were immunoprecipitated with mouse anti-Flag mAb, followed by western blotting with rabbit anti-Flag pAb, rabbit anti-HA pAb, and rabbit anti-V5 pAb. The data are representative of at least three independent experiments
