The influenza A virus NS1 protein inhibits activation of Jun N-terminal kinase and AP-1 transcription factors

J Virol. 2002 Nov;76(21):11166-71. doi: 10.1128/jvi.76.21.11166-11171.2002.

Abstract

The influenza A virus nonstructural NS1 protein is known to modulate host cell gene expression and to inhibit double-stranded RNA (dsRNA)-mediated antiviral responses. Here we identify NS1 as the first viral protein that antagonizes virus- and dsRNA-induced activation of the stress response-signaling pathway mediated through Jun N-terminal kinase.
