The Acute Myeloid Leukemia-Associated Protein, Dek, Forms a Splicing-Dependent Interaction with Exon-Product Complexes
Bibliographic record
Abstract
DEK is an approximately 45-kD phosphoprotein that is fused to the nucleoporin CAN as a result of a (6;9) chromosomal translocation in a subset of acute myeloid leukemias (AMLs). It has also been identified as an autoimmune antigen in juvenile rheumatoid arthritis and other rheumatic diseases. Despite the association of DEK with several human diseases, its function is not known. In this study, we demonstrate that DEK, together with SR proteins, associates with the SRm160 splicing coactivator in vitro. DEK is recruited to splicing factor-containing nuclear speckles upon concentration of SRm160 in these structures, indicating that DEK and SRm160 associate in vivo. We further demonstrate that DEK associates with splicing complexes through interactions mediated by SR proteins. Significantly, DEK remains bound to the exon-product RNA after splicing, and this association requires the prior formation of a spliceosome. Thus, DEK is a candidate factor for controlling postsplicing steps in gene expression that are influenced by the prior removal of an intron from pre-mRNA.

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.
