Actin patch assembly proteins Las17p and Sla1p restrict cell wall growth to daughter cells and interact with <i>cis</i>‐Golgi protein Kre6p
Bibliographic record
Abstract
The cytoplasmic tail of Kre6p, a Golgi membrane protein involved in cell wall synthesis, interacts with the actin patch assembly components Las17p and Sla1p in a two-hybrid assay, and Kre6p co-immunoprecipitates with Las17p. Kre6p showed extensive co-localization with Och1p-containing cis-Golgi vesicles. The correct localization of Kre6p requires its cytoplasmic tail, Las17p, Sla1p and Vrp1p, suggesting that the cytoplasmic tail of Kre6p acts as a receptor, linking this cis-Golgi protein to Las17p and Sla1p. The actin patch assembly mutants las17 delta, sla1delta and vrp1 delta showed elevated levels of cell wall beta-1,6-glucan, and mutant cells were capable of only a limited number of cell divisions compared to wild-type. EM image analysis and beta-1,6-glucan localization indicated abnormal wall proliferation in the mother cells of these mutants. The pattern of cell wall hypertrophy indicates a failure to restrict cell wall growth to the bud.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
