RNF proteins modulate the RLR signaling pathway. Following the recognition of distinct dsRNA features by RIG-I and MDA5, their CARDs recruit and activate the downstream adaptor protein MAVS to trigger IRF3 and NF-κB activation, resulting in the production of IFN-I and inflammatory cytokines. RNF proteins emerged as key regulators via positively (green arrows) or negatively (red T-shaped solid line) modulating the RLR signaling pathway. P, phosphate
