Forkhead followed by disordered tail: The intrinsically disordered regions of FOXO3a
Bibliographic record
Abstract
Forkhead box Class O is one of 19 subfamilies of the Forkhead box family, comprising 4 human transcription factors: FOXO1, FOXO3a, FOXO4, and FOXO6, which are involved in many crucial cellular processes. FOXO3a is a tumor suppressor involved in multiple physiological and pathological processes, and plays essential roles in metabolism, cell cycle arrest, DNA repair, and apoptosis. In its role as a transcription factor, the FOXO3a binds a consensus Forkhead response element DNA sequence, and recruits transcriptional coactivators to activate gene transcription. FOXO3a has additional functions, such as regulating p53-mediated apoptosis and activating kinase ATM. With the exception of the structured DNA-binding forkhead domain, most of the FOXO3a sequence comprises intrinsically disordered regions (IDRs), including 3 regions (CR1-3) that are conserved within the FOXO subfamily. Numerous studies have demonstrated that these IDRs directly mediate many of the diverse functions of FOXO3a. These regions contain post-translational modification and protein-protein interaction sites that integrate upstream signals to maintain homeostasis. Thus, the FOXO3a IDRs are emerging as key mediators of diverse regulatory processes, and represent an important target for the future development of therapeutics for FOXO3a-related diseases.

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.
