AP‐1 is a transcription factor (TF) complex that regulates gene expression programs in response to diverse stimuli, including stress, viral infections (Hess et al., 2004), and pro‐inflammatory signals in concert with the NF‐KB pathway (Fujioka et al., 2004; Ji et al., 2019; Renoux et al., 2020). Here, JUND is linked to viral infectious disease.
