<i>Amsacta moorei</i> Entomopoxvirus Inhibitor of Apoptosis Suppresses Cell Death by Binding Grim and Hid
Bibliographic record
Abstract
Inhibitor of apoptosis (iap) genes have been identified in the genomes of two independent families of insect viruses, the Baculoviridae and the Entomopoxvirinae. In this report, we examined the functional attributes of the Amsacta moorei entomopoxvirus-encoded IAP protein (AMV-IAP). The binding specificity of the individual baculoviral IAP repeat (BIR) domains of AMV-IAP was investigated by using a random-peptide, phage display library, and sequences similar to the amino termini of proapoptotic Drosophila proteins in the Reaper/Hid/Grim family were identified. Furthermore, the BIR domains of AMV-IAP protein were demonstrated to bind the mammalian IAP inhibitor Smac through the AVPI tetrapeptide sequence, suggesting that the peptide binding pocket and groove found in the insect and mammalian IAPs is conserved in this viral protein. Interaction analysis implicated BIR1 as the high-affinity site for Grim, while BIR2 interacted more strongly with Hid. Both Grim and Hid were demonstrated to interact with AMV-IAP in vivo, and Grim- or Hid-induced cell death was suppressed when AMV-IAP was coexpressed.

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.
