Expression patterns of ShcD and Shc family adaptor proteins during mouse embryonic development
Bibliographic record
Abstract
The Src homology and collagen (Shc) proteins function as molecular adaptors in signaling pathways mediated by a variety of cell surface receptors. Of the four mammalian Shc proteins, ShcD is the least characterized. To this end, ShcD expression was documented and compared to that of other Shc family proteins. In the developing mouse embryo, expression of ShcD overlaps with that of other Shc proteins in the central nervous system, with specific distribution in post-mitotic neurons. In addition, robust ShcD expression is seen within differentiated epithelial cells of several organs, as well as in skeletal and cardiac muscle, and various tissues of neural crest origin. Interestingly, all Shc family members are expressed in hypertrophic chondrocytes, the first report of Shc protein expression in the developing skeleton. The unique tissue distribution patterns of Shc proteins likely contribute to their complex tissue-specific signaling functions during embryogenesis.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
