Rajsbaum, Ricardo A. Albrecht, Randy K. Wang, May P. Maharaj, Natalya A. Versteeg, Gijs Nistal-Villán, Estanislao García-Sastre, Adolfo U. Gack, Michaela Influenza A Virus NS1 interacts with mouse Riplet. <p>(<b>A</b>) At 30 h posttransfection with Myc-tagged mouse Riplet (Myc-mRiplet) together with NS1-PR8, HEK293T cells were mock-treated or infected with SeV (10 HA units/ml) for 10 h. V5-tagged hTRIM25 was co-transfected as positive control. WCLs were subjected to IP with anti-Myc (Riplet) or anti-V5 (TRIM25), followed by IB with anti-NS1 antibody. (<b>B</b>) Hepa1.6 cells were transfected with Flag-tagged mouse Riplet. At 30 h posttransfection, cells were either mock-treated or infected with recombinant A/PR/8/34 virus at an MOI of 2. 18 h later, WCLs were subjected to IP with anti-NS1 antibody, followed by immunoblotting using the indicated antibodies. (<b>C</b>) Localization of NS1-PR8 and mouse Riplet in HeLa cells determined by confocal microscopy. At 30 h posttransfection with Myc-mRiplet alone, NS1-PR8 alone, or NS1 together with Myc-mRiplet, HeLa cells were stained with anti-Myc (green), anti-NS1 (red), and DAPI (nucleus, blue). Fifty cells from three independent experiments were counted and the percentage of cells with cytoplasmic NS1 is shown, ***p<0.001 by Fisher's exact test. (<b>D and E</b>) Hepa1.6 cells were transfected with Flag-tagged mouse Riplet. At 30 h posttransfection, cells were either mock-treated or infected with recombinant A/PR/8/34 virus expressing NS1 PR8, Cal04, HK156, Tx91, SwTx98, or Pan99 at an MOI of 2 (<b>D</b>), or R38A/K41A or E96A/E97A NS1 mutant at an MOI of 4 (<b>E</b>). 18 h later, WCLs were subjected to IP with anti-NS1 antibody, followed by immunoblotting using the indicated antibodies.</p> ns1;interacts 2012-11-29
