Abstract
Angiostatin is a potent inhibitor of angiogenesis. One mechanism through which angiostatin inhibits angiogenesis is by binding to the cell surface protein p80-angiomotin. The p80-angiomotin protein promotes angiogenesis, in part, by conferring a hypermigratory phenotype to endothelial cells. Although p80-angiomotin is extensively characterized, less is known about the related protein angiomotin-like 1. We report that angiomotin-like 1 forms part of a protein complex containing p80-angiomotin. Structure-function studies revealed that angiomotin-like 1 associates with this p80-angiomotin-containing complex via its coiled-coil domain. Since p80-angiomotin plays a role in cell migration, a process that involves the remodeling of the actin cytoskeleton, we then addressed the hypothesis that angiomotin-like 1 may interact with the cytoskeleton. Immunofluorescence studies reveal that angiomotin-like 1 not only co-localizes with filamentous actin but also significantly modifies the architecture of the actin cytoskeleton. Regarding migration, angiomotin-like 1 increases the velocity of migration and decreases the persistence of migration directionality. Together these observations strongly suggest that angiomotin-like 1 is involved in actin-cytoskeleton-based processes, in part, via its interaction with a p80-angiomotin-containing complex and the actin cytoskeleton. These findings have important implications for angiogenesis-driven disease since angiomotin and angiomotin-like 1 are both expressed in capillaries.

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 it
