However, the zinc-finger antiviral protein (ZAP), an important mediator of cellular response to retroviruses, 39 alphaviruses, 40 and filoviruses, 41 has been shown to bind the hRrp46 component of the exosome and to recruit the complex to viral mRNAs to promote their degradation. Nonetheless, given the widespread roles for the exosome in RNA quality control and turnover, viruses presumably activate this complex at least indirectly when triggering turnover of cellular mRNAs. For example, infection by select herpes and coronaviruses results in a global destruction of host messages. ./cache/cord-271972-qhr6iir6.txt ./txt/cord-271972-qhr6iir6.txt
