Molecular cloning of Ca<i>YRB1</i>, the <i>Candida albicans</i> RanBP1/YRB1 homologue
Bibliographic record
Abstract
The yeast Ran binding protein 1 (Yrb1p) is a small protein of 23 kDa that is highly conserved among eukaryotes. It stimulates the GTPase activity of Gsp1p in the presence of the GTPase activating protein Rna1p. In addition to its role in nucleocytoplasmic transport of macromolecules, YRB1/RanBP1 could be involved in the regulation of microtubules structure and dynamics. Since microtubules are tightly associated with morphological changes, we have been interested to study the role and function of YRB1 in the pathogenic fungus Candida albicans, where there is regulated change in cellular morphology. The gene product of CaYRB1 encodes a 212 amino acid protein displaying 73% homology to the S. cerevisiae homologue. The bacterially expressed gene product has an apparent molecular weight of 35.7 kDa. We show that it can complement a S. cerevisiae yrb1 null mutant and that its mRNA does not appear to be regulated in response to conditions inducing morphological changes in C. albicans.

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.
