Abstract

fetched live from OpenAlex

Multiple screens performed in Drosophila, Caenorhabditis elegans, Xenopus, and zebrafish have identified dozens of proteins participating in Wnt signal transduction. Epistasis experiments, enhancer and suppressor screens, and protein-protein interaction techniques have also been efficient at finding new pathway members, connecting proteins together, and establishing the architectural framework of how the Wnt signaling pathway functions. In the last few years, spectacular technological breakthroughs in the field of mass spectrometry have allowed the study of proteins and peptides with unprecedented sensitivity and accuracy. Recently, we have developed methods to study the Wnt pathway using mass spectrometry by studying the composition of protein complexes isolated from mammalian cells. In addition to identifying novel proteins acting in this pathway, this approach is providing information about the supramolecular organization of the protein complexes in the pathway and how the individual proteins are activated and regulated. This chapter details the experimental procedure that we developed to study mammalian protein complexes using a gel-free mass spectrometry approach.

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.

Not 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.
