Abstract

fetched live from OpenAlex

An essential step of protein function analysis is to discover patterns that represent functional regions in a set of protein family sequences. However, the same functional region of a protein family that occurs in different sequences may contain variations that resulted from biological substitutions, deletions, and insertions. Thus, a sequence pattern representing this functional region seldom repeats precisely at the exact position with the same amino acid residues. To capture these variable associations, we developed a pattern synthesis process. First, we used an effective sequence pattern discovery algorithm to discover high order patterns as input. Next, we group and align these similar discovered patterns into Aligned Random Pattern Clusters (ARPCs). During the clustering process, each ARPC is transformed into a probabilistic structural pattern called the Aligned Random Pattern Digraph (ARPD). The advantages of our synthesis process are 1) the synthesized patterns are not confined to a fixed protein region since the ARPCs captures the similar patterns by their variable sites, 2) the ARPDs retain both horizontal pattern associations and vertical site variations, and 3) the search space for synthesizing input patterns is smaller than that for aligning input sequences. Our method successfully discovers two functional protein regions of the Cytochrome Complex protein family: the proximal and distal binding segment that binds the iron molecule of the heme ligand from each side of the plane without relying on prior knowledge.

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.
