Abstract
Intrinsically disordered proteins (IDPs) are widespread in eukaryotes and fulfill important functions associated with signaling and regulation. Recent evidence points to a special and thus largely disrespected functional capacity of IDPs--that they can assist the folding of other proteins and prevent their aggregation, i.e., that they can act as chaperones. In this paper, we survey current information available on this phenomenon, with particular focus on (i) the structure and function of IDPs in general, (ii) disordered chaperones in plants, (iii) disordered chaperones in other organisms spanning from insects to mammals, (iv) the possible mechanisms of action of disordered chaperones, and (v) the possibility of two-faced (Janus) chaperone activity of disordered chaperones, which can assist the folding of both RNA and protein substrates. The evidence is most conclusive in the case of plant stress proteins, such as late embryogenesis abundant (LEA) proteins or dehydrins. We will show that the cellular function of LEA proteins in mitigating the damage caused by stress is clear; nevertheless, experiments carried out in vivo must be extended and the molecular mechanism of the action of IDP chaperones also requires clarification. Using these details, we chart out how far the field has progressed only to emphasize the long road ahead before chaperone function can be firmly established as part of the physiological mechanistic arsenal of the emerging group of IDPs.

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
