#1 SGMS1-Driven Sphingomyelin Accumulation Impairs BACE1 Lysosomal Degradation via Autophagosome-Lysosome Fusion Dysfunction
0.542
SGMS1, BECN1
Elevated SGMS1 activity increases sphingomyelin levels in neuronal membranes, disrupting autophagosome-lysosome fusion and preventing lysosomal degradation of BACE1. This leads to BACE1 accumulation i
