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.

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.
