Abstract
The Tudor domain is an approximately 60-amino acid structure motif in search of a function. Herein we show that the Tudor domains of the spinal muscular atrophy gene product SMN, the splicing factor 30 kDa (SPF30), and the Tudor domain-containing 3 (TDRD3) proteins interacted with arginine-glycine-rich motifs in a methylarginine-dependent manner. The Tudor domains also associated with methylarginine-containing cellular proteins, providing evidence that methylated arginines represent physiological ligands for this protein module. In addition, we report that spliceosomal small nuclear ribonucleoprotein particles core Sm proteins accumulated in the cytoplasm when arginine methylation was inhibited with adenosine dialdehyde or in the presence of an excessive amount of unmethylated arginine-glycine-rich peptides. These data provide in vivo evidence in support of a role for arginine methylation in the proper assembly and localization of spliceosomal Sm proteins.

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
