Abstract
Ribonucleoprotein (RNP) granules play a major role in compartmentalizing cytoplasmic RNA regulation. Haploid round spermatids that have exceptionally diverse transcriptomes are characterized by a unique germ cell-specific RNP granule, the chromatoid body (CB). The CB shares many characteristics with somatic RNP granules but also has germline-specific features. The CB appears to be a central structure in PIWI-interacting RNA (piRNA)-targeted RNA regulation. Here, we identified a novel CB component, FYCO1, which is involved in the intracellular transport of autophagic vesicles in somatic cells. We demonstrated that the CB is associated with autophagic activity. Induction of autophagy leads to the recruitment of lysosomal vesicles onto the CB in a FYCO1-dependent manner as demonstrated by the analysis of a germ cell-specific Fyco1 conditional knockout mouse model. Furthermore, in the absence of FYCO1, the integrity of the CB was affected and the CB was fragmented. Our results suggest that RNP granule homeostasis is regulated by FYCO1-mediated autophagy.

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
