The 70‐kDa protein bound to hsp90 in wheat germ lysate is a plant homologue of animal Hop
Bibliographic record
Abstract
The hsp90‐based chaperone machinery is implicated in numerous cellular processes including signal transduction, genomic silencing, and protein degradation. Hop is a component of the animal hsp90 multichaperone complex, whose function is to link the two chaperones, hsp90 and hsp70. Currently there exists little information on a plant Hop homologue. Herein it is reported that a 70‐kDa protein in wheat germ lysate is associated with hsp90 and hsp70 and that this protein is a wheat homologue of Hop. It is also shown that, in addition to being detected in complexes, the wheat Hop as well as the previously identified immunophilin FKBP73, can bind directly to purified plant hsp90. In the steroid receptor folding assay, the wheat Hop was not detected in receptor complexes, but the wheat immunophilin FKBP73 could be detected when mammalian p23 was added to the plant lysate. The present results identify two hsp90‐binding proteins and provide a useful framework on which to further investigate their functions.

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.
