snz/SNX25 at the crossroad of endocytosis and lipid handling in autophagy
Bibliographic record
Abstract
Macroautophagy/autophagy is coupled to a myriad of intracellular processes, among which vesicular trafficking is an important contributor of membranes and proteins required at various stages, from autophagosome formation to degradation. Hence, understanding how membrane trafficking is coupled to autophagy induction and how cells rewire trafficking upon high autophagic needs is instrumental to our understanding of autophagy. In our recent manuscript, we tested a known class of endosomal sorting regulators, the sorting nexin family, for their involvement in autophagy in Drosophila. We identified snz (snazarus) as an important regulator of autophagy in Drosophila as well as in mammalian cells, by demonstrating a role for the snz human ortholog SNX25 in HeLa cells. Using knockout rescue experiments, we observed that SNX25 loss affects many cellular processes, namely VAMP8 endocytosis and lipid handling. Mutational studies identified separate protein domains involved in these processes. Given the role of this sorting nexin family in lipid droplet regulation, our work expands their requirement to autophagy.

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.
