Neuronal sorting protein-related receptor sorLA/LR11 regulates processing of the amyloid precursor protein
36/100 ✓ Peer-reviewed Risk genes beyond APOE Proceedings of the National Academy of Sciences of the United States of America
Key finding: Overexpression of sorLA in neurons causes redistribution of APP to the Golgi and decreased processing to Abeta, whereas ablation of sorLA expression in knockout mice results in increased levels of Abeta in the brain similar to the situation in AD patients.
