MCPIP1 ribonuclease exhibits broad-spectrum antiviral effects through viral RNA binding and degradation.

Monocyte chemoattractant protein 1-induced protein 1 (MCPIP1), belonging to the MCPIP family with highly conserved CCCH-type zinc finger and Nedd4-BP1, YacP Nuclease domains, has been implicated in negative regulation of the cellular inflammatory responses. In this report, we demonstrate for the first time that this RNA-binding nuclease also targets viral RNA and possesses potent antiviral activities. Overexpression of the human MCPIP1, but not MCPIP2
