Prp8 intein in fungal pathogens: target for potential antifungal drugs
Bibliographic record
Abstract
Inteins are self-splicing intervening sequences in proteins, and inteins of pathogenic organisms can be attractive drug targets. Here, we report an intein in important fungal pathogens including Aspergillus fumigatus, Aspergillus nidulans, Histoplasma capsulatum, and different serotypes of Cryptococcus neoformans. This intein is inside the extremely conserved and functionally essential Prp8 protein, and it varies in size from 170 aa in C. neoformans to 819 aa in A. fumigatus, which is caused by the presence or absence of an endonuclease domain and a putative tongs subdomain in the intein. Prp8 inteins of these organisms were demonstrated to do protein splicing in a recombinant protein in Escherichia coli. These findings revealed Prp8 inteins as attractive targets for potential antifungal drugs to be identified using existing selection and screening methods.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
