Co-immunoprecipitation assays confirmed the interaction between N protein and Dicer, exportin 5 (XPO5), serine/arginine-rich splicing factor 3 (SRSF3), and heterogeneous nuclear ribonucleoprotein A3 (hnRNPA3) in human lung cancer (A549) and human normal lung epithelial (BEAS-2B) cell lines ectopically expressing N protein (Fig. 1e and Supplementary Fig. 2a). The gene discussed is HNRNPA3; the disease is lung carcinoma.
