Differentiating the Roles of UL16, UL21, and Us3 in the Nuclear Egress of Herpes Simplex Virus Capsids
Bibliographic record
Abstract
The membrane deformation activity of the herpesvirus nuclear egress complex (NEC) allows capsids to transit through both nuclear membranes into the cytoplasm. NEC activity must be precisely controlled during viral infection, and yet our knowledge of how NEC activity is controlled is incomplete. To determine how pUL16 and pUL21, two viral proteins required for nuclear egress of herpes simplex virus 2, function in nuclear egress, we examined how the lack of each protein impacted NEC distribution. These analyses revealed a function of pUL16 in nuclear egress distinct from that of pUL21, uncovered a novel role for pUL21 in regulating NEC activity, and shed new light on how a viral kinase, pUs3, regulates nuclear egress. Nuclear egress of capsids is required for all herpesviruses. A complete understanding of all aspects of nuclear egress, including how viral NEC activity is controlled, may yield strategies to disrupt this process and aid the development of herpes-specific antiviral therapies.

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.
