| Post Translational Modifications | Phosphorylated. The non-phosphorylated form(s) exhibited the strongest poly(rC)-binding activity. (Microbial infection) Proteolytically cleaved by picornavirus proteinase 3CD. |
| Function | Single-stranded nucleic acid binding protein that binds preferentially to oligo dC. Major cellular poly(rC)-binding protein. Binds also poly(rU). Acts as a negative regulator of antiviral signaling. Negatively regulates cellular antiviral responses mediated by MAVS signaling. It acts as an adapter between MAVS and the E3 ubiquitin ligase ITCH, therefore triggering MAVS ubiquitination and degradation. Negativeley regulates the cGAS-STING pathway via interaction with CGAS, preventing the formation of liquid-like droplets in which CGAS is activated. Together with PCBP1, required for erythropoiesis, possibly by regulating mRNA splicing. (Microbial infection) In case of infection by poliovirus, binds to the viral internal ribosome entry site (IRES) and stimulates the IRES-mediated translation. Also plays a role in initiation of viral RNA replication in concert with the viral protein 3CD. |
