- obsolete suppression by virus of host RIG-I K63-linked ubiquitination
OBSOLETE. Any process in which a virus stops, prevents, or reduces the rate or extent of K63-linked ubiquitination of RIG-I (also known as DDX58), thereby suppressing RIG-I signal transduction. Lys63-linked ubiquitination of the N-terminal CARD domains of RIG-I is crucial for the cytosolic RIG-I signaling pathway to elicit host antiviral innate immunity.
- obsolete suppression by virus of host RIG-I activity by viral RNA 5' processing
OBSOLETE. The post-transcriptional removal by a virus of the 5' triphosphate group of their viral RNA, thereby preventing host RIG-I from recognizing viral RNA in the host cell. The intracellular pattern recognition receptor RIG-I (also known as DDX58) recognizes viral RNAs containing 5' triphosphates; removal by the virus of the 5'-terminal triphosphate group from their genome protects the viral RNA from RIG-recognition.
- RIG-I binding
Binding to RIG-I, a cytosolic pattern recognition receptor that initiates an antiviral signaling pathway upon binding to viral RNA.
- RIG-I signaling pathway
The series of molecular signals initiated by the binding ssRNA or dsRNA from another organism to the cytoplasmic pattern recognition receptor (PRR) RIG-1 (also known as DDX58). RIG-I detects RNA synthesized during viral replication or shed by non-viral pathogens, and triggers a signaling pathway to protect the host against infection, for example by inducing the expression of cytokines.
