[LRP1](/proteins/lrp1-protein) (Low-Density Lipoprotein Receptor-Related Protein 1) is a large endocytic receptor involved in the clearance of multiple ligands including [amyloid-beta](/proteins/amyloid-beta) (Aβ), apolipoprotein E (ApoE), and various signaling molecules. LRP1 plays a crucial role in maintaining brain homeostasis and its dysfunction is implicated in Alzheimer's disease (AD) and other neurodegenerative disorders.
LRP1 is one of the largest membrane receptors, characterized by:
In the healthy nervous system, LRP1 functions as:
LRP1 is critical in AD pathogenesis through its role in Aβ metabolism:
In PD, LRP1:
LRP1 activates diverse intracellular signaling cascades:
Key signaling molecules:
