SHC-3: a previously unidentified <i>C. elegans</i> Shc family member functions in the insulin-like signaling pathway to enhance survival during L1 arrest
Bibliographic record
Abstract
Shc (Src homologous and collagen) proteins function in many different signaling pathways where they mediate phosphorylation-dependent protein-protein interactions. These proteins are characterized by the presence of two phosphotyrosine-binding domains, an N-terminal PTB and a C-terminal SH2. We describe a previously unrecognized Caenorhabditis elegans Shc gene, shc-3 and characterize its role in stress response. Both shc-3 and shc-1 are required for long-term survival in L1 arrest and survival in heat stress, however, they do not act redundantly but rather play distinct roles in these processes. Loss of shc-3 did not further decrease survival of daf-16 mutants in L1 arrest, suggesting that like SHC-1, SHC-3 functions in the insulin-like signaling pathway. In the absence of SHC-3, DAF-16 nuclear entry and exit are slowed, suggesting that SHC-3 is required for rapid changes in DAF-16 signaling.

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.
