On viral infection poly(rC) binding protein 2 (PCBP2) binds mitochondrial antiviral signaling protein (MAVS or IPS-1) and recruits the HECT domain-containing E3 ligase AIP4 (or ITCH) (You F et al. 2009). ITCH catalyses K48-linked polyubiquitination to trigger degradation of MAVS via the proteasomal pathway. Severe acute respiratory syndrome coronavirus-1 (SARS-CoV-1) 9b (ORF9b) suppresses the MAVS-mediated signaling pathway by facilitating the recruitment of PCBP2 and ITCH to MAVS during viral infection (Shi CS et al. 2014).
