Identification of influenza virus nucleoprotein (NP)-associated factors by immunoprecipitation-mass spectrometry (IP/MS). (A,B) Eluates of duplicate hemagglutinin (HA) immunoprecipitates from HA-NP overexpressed DF-1 cells were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and silver staining. (C–G) DF-1 cells were transfected with three different chaperonin containing TCP1 subunit 5 (CCT5), phenylalanyl-tRNA synthetase, alpha subunit (FARSA), RuvB-like AAA ATPase 1 (RUVBL1), NOP56, methylenetetrahydrofolate dehydrogenase (NADP+ dependent) 1-like (MTHFD1L) small interfering RNAs (siRNAs) as indicated for 24 h. Knockdown efficiency was determined by real-time PCR and Western blot. The data are presented as the means ± SD from three independent experiments (*p < 0.05; **p < 0.01; ***p < 0.001, by t-test).
