COMMD5/HCaRG Hooks Endosomes on Cytoskeleton and Coordinates EGFR Trafficking
Bibliographic record
Abstract
COMMD5/HCaRG is involved in tissue repair, and its low expression is associated with tumorigenicity. Cell growth, migration, and differentiation are controlled by COMMD5. We previously reported that COMMD5 inhibited the growth of renal carcinoma cells by regulating expression or phosphorylation of ErbB members. Here, we demonstrate that COMMD5 is crucial for the stability of the cytoskeleton. Its silencing leads to a major re-organization of actin and microtubule networks. The N terminus of COMMD5 binds to the endosomal Rab5, and its C terminus, including the COMMD domain, binds to the cytoskeletal scaffolding. COMMD5 participates in long-range endosome transport, including epidermal growth factor receptor (EGFR) recycling, and provides the strength to deform and assist the scission of vesicles into sorting endosomes. This study establishes the molecular mechanism by which COMMD5 acts as an adaptor protein to coordinate endosomal trafficking and reveals its important role for EGFR transport and activity.

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.
