Cellular and antiviral functions of TRIM5α
Bibliographic record
Abstract
In this review, we summarize recent advances in the knowledge of the biological functions of human TRIM5α, a cytoplasmic protein mostly known for its antiretroviral functions. In addition to directly targeting retroviral capsid cores, an inhibitory activity called "restriction", TRIM5α senses retroviruses and activates NF-κB and AP-1 signaling pathways, resulting in the production of type I interferon (IFN-I). The antiviral state resulting from the activation of these pathways includes the upregulation of other restriction factors, and is thought to be important for the control of HIV-1 in some patients. TRIM5α also targets the protease enzyme of several tick-borne flaviviruses, a family of viruses not closely related to retroviruses. In addition to these antiviral functions, TRIM5α promotes autophagy by interacting with key actors of this pathway, such as ULK1 and p62. TRIM5α may function as a selective autophagy receptor in some conditions. Altogether, our understanding of TRIM5α shows its potential for the development of medical applications in viral diseases and beyond.

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.
