mtRBP complex AMG-1/SLRP-1 mediates germline development and spermatogenesis by maintaining mitochondrial homeostasis in Caenorhabditis elegans
Bibliographic record
Abstract
Abstract The RNA-binding proteins (RBPs)-mediated post-transcriptional regulation of pre-existing mRNAs is essential for spermatogenesis. But the underlying mechanisms remain poorly understood. Here, we identify a germline-specific mitochondrial RBP AMG-1, a homolog of mammalian LRPPRC, required for spermatogenesis in C. elegans. amg-1 mutation leads to the germline-specific mitochondrial dysfunctions associated with aberrant mitochondrial morphology and structure, which eventually hinders germline development without affecting somatic development. We demonstrate that AMG-1 most frequently binds to mitochondrial DNA-encoded 16S and 12S ribosomal RNAs, the essential components of mitochondrial ribosome, and that 12S rRNA expression mediated by AMG-1 is crucial for germline mitochondrial protein homeostasis. Besides, mitochondrial dysfunction caused by AMG-1 mutation triggers sperm apoptosis in C. elegans. Furthermore, SLRP-1, the homolog of mammalian SLIRP in C. elegans, interacts with AMG-1 genetically to regulate germline development and reproductive success. Taken together, these findings reveal the novel function of a mitochondrial RBP in specifically regulating germline development.

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.
