Antagonizing Scalloped With a Novel Vestigial Construct Reveals an Important Role for Scalloped in <i>Drosophila melanogaster</i> Leg, Eye and Optic Lobe Development
Bibliographic record
Abstract
Scalloped (SD), a TEA/ATTS-domain-containing protein, is required for the proper development of Drosophila melanogaster. Despite being expressed in a variety of tissues, most of the work on SD has been restricted to understanding its role and function in patterning the adult wing. To gain a better understanding of its role in development, we generated sd(47M) flip-in mitotic clones. The mitotic clones had developmental defects in the leg and eye. Further, by removing the VG domains involved in activation, we created a reagent (VGDeltaACT) that disrupts the ability of SD to form a functional transcription factor complex and produced similar phenotypes to the flip-in mitotic clones. The VGDeltaACT construct also disrupted adult CNS development. Expression of the VGDeltaACT construct in the wing alters the cellular localization of VG and produces a mutant phenotype, indicating that the construct is able to antagonize the normal function of the SD/VG complex. Expression of the protein:protein interaction portion of SD is also able to elicit similar phenotypes, suggesting that SD interacts with other cofactors in the leg, eye, and adult CNS. Furthermore, antagonizing SD in larval tissues results in cell death, indicating that SD may also have a role in cell survival.

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.
