Interaction between MARCH2 and NEMO in response to viral infection. Raw264.7 cells (F) were infected with NDV-GFP in a time-dependent manner in the presence of MG132 (proteasome inhibitor, 10 μM). Cell lysates were subjected to immunoprecipitation with an anti-NEMO antibody, followed by immunoblotting with an anti-MARCH2 antibody.
