How does polyglutamine expansion affect huntingtin's KFERQ-like motif recognition by CMA machinery?

OPEN

The abstract mentions that CMA requires KFERQ-like motifs for substrate recognition and that mutant Htt with expanded polyglutamine is a CMA substrate, but doesn't explain how the pathogenic expansion influences motif accessibility or chaperone binding. This mechanistic gap is crucial for understanding CMA efficiency in disease.
