ASFV pS183L protein negatively regulates RLR-mediated antiviral signalling by blocking MDA5 oligomerisation
Bibliographic record
Abstract
Abstract The retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs) are major sensors against viral infection, but their roles in DNA virus infection largely remain unknown. This study found that a previously uncharacterised protein, pS183L, negatively regulates RLR signalling by suppressing MDA5 oligomerisation. Specifically, we showed that the overexpression of pS183L suppresses MDA5 but not cGAS-STING or RIG-I-induced IFN-β activation. Consistently, pS183L inhibited high molecular weight poly (I:C) activated IFN-β production. Furthermore, we demonstrated that pS183L interacts with CARDs and the MDA5 Helicase domain, consequently blocking MDA5 oligomerisation and the MDA5-MAVS interaction. Taken together, we concluded that pS183L blocks MDA5 oligomerisation through protein–protein interaction and thus disrupts MDA5-mediated IFN-β signalling.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
