Abstract
Origin recognition complex (ORC) proteins were first discovered as a six-subunit assemblage in budding yeast that promotes the initiation of DNA replication. Orc1-5 appear to be present in all eukaryotes, and include both AAA+ and winged-helix motifs. A sixth protein, Orc6, shows no structural similarity to the other ORC proteins, and is poorly conserved between budding yeast and most other eukaryotic species. The replication factor Cdc6 has extensive sequence similarity with Orc1 and phylogenetic analysis suggests the genes that encode them may be paralogs. ORC proteins have also been found in the archaea, and the bacterial DnaA replication protein has ORC-like functional domains. In budding yeast, Orc1-6 are bound to origins of DNA replication throughout the cell cycle. Following association with Cdc6 in G1 phase, the sequential hydrolysis of Cdc6 - then ORC-bound ATP loads the Mcm2-7 helicase complex onto DNA. Localization of ORC subunits to the kinetochore and centrosome during mitosis and to the cleavage furrow during cytokinesis has been observed in metazoan cells and, along with phenotypes observed following knockdown with short interfering RNAs, point to additional roles at these cell-cycle stages. In addition, ORC proteins function in epigenetic gene silencing through interactions with heterochromatin factors such as Sir1 in budding yeast and HP1 in higher eukaryotes. Current avenues of research have identified roles for ORC proteins in the development of neuronal and muscle tissue, and are probing their relationship to genome integrity.

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
