Identification and characterization of new cellular interacting proteins of HIV-1 integrase
Bibliographic record
Abstract
HIV-1 integrase (IN) enzyme employs several viral and cellular proteins for nuclear translocation and crucial integration of viral cDNA. Successful identification of new viral/cellular interactions may shed light for better understanding of HIV-1 replication. 293T cells were transiently transfected with pYEF-1-TAP-IN and cell lysate were subjected to Tandem Affinity Purification system to pull down putative IN-interacting cellular partners. A number of distinct bands from the Coomassie-stained gel were excised followed by in-gel digestion and mass spectrometry. Putative cellular partners of HIV-1 IN were heat shock protein 60 (HSP60), β-tubulin, γ-actin, ATP synthase alpha subunit and histone H1.2 were identified by mass spectrometry. Additionally, SF3A3 (splicing factor 3A3), another previously reported factor, was successfully co-immunoprecipitated with IN. The C-terminal portion of IN was found to be the region of interaction with SF3A3. Overall, this study has provided better understanding of IN dynamics enriching existing knowledge of HIV-1 IN biology.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
