Abstract

fetched live from OpenAlex

Calmodulin (CaM) is an important calcium (Ca 2+ ) sensor in the cell and is able to activate over three hundred proteins to initiate cellular activities. CaM is a highly dynamic protein with a flexible central linker region joining the N‐terminal and C‐terminal domains. In each domain are two Ca 2+ binding sites that cause structural changes to CaM when Ca 2+ binds. These changes include the CaM central linker elongating and methionine rich hydrophobic patches being exposed, allowing for CaM to bind to the large population of target proteins. The structural interaction of CaM to short peptides from the CaM binding region of various target enzymes were investigated, including the nitric oxide synthase (NOS) enzyme.

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 distilled prediction

Teacher imitation

Not 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.
