Abstract

fetched live from OpenAlex

Lipid phosphate phosphatase-1 (LPP-1) dephosphorylates exogenous lysophosphatidate and thereby regulates the activation of lysophosphatidate receptors and cell division. Mutation of seven amino acids in three conserved domains of mouse LPP-1 abolished its activity. A glycosylation site was demonstrated between conserved Domains 1 and 2. LPP-1 is expressed in the plasma membrane, and the present results demonstrate the active site to be located on the outer surface.

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.
