== Publication Abstract from PubMed == | |||
SorLA is a neuronal sorting receptor considered to be a major risk factor for Alzheimer's disease. We have recently reported that it directs lysosomal targeting of nascent neurotoxic amyloid-beta (Abeta) peptides by directly binding Abeta. Here, we determined the crystal structure of the human sorLA domain responsible for Abeta capture, Vps10p, in an unbound state and in complex with two ligands. Vps10p assumes a ten-bladed beta-propeller fold with a large tunnel at the center. An internal ligand derived from the sorLA propeptide bound inside the tunnel to extend the beta-sheet of one of the propeller blades. The structure of the sorLA Vps10p-Abeta complex revealed that the same site is used. Peptides are recognized by sorLA Vps10p in redundant modes without strict dependence on a particular amino acid sequence, thus suggesting a broad specificity toward peptides with a propensity for beta-sheet formation. | |||
