Poly(rC)-binding protein 2 (PCBP2) is a single-stranded nucleic acid binding protein that binds preferentially to oligo dC, It is also named Heterogeneous nuclear ribonucleoprotein E2, binds also poly(rU). It 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 ubiquitinationa and degradation.(19881509) This antibody can recognize PCBP2 and PCBP1.
PCBP2 maintains antiviral signaling homeostasis by regulating cGAS enzymatic activity via antagonizing its condensation.
