Function

[LRP1_HUMAN] Endocytic receptor involved in endocytosis and in phagocytosis of apoptotic cells. Required for early embryonic development. Involved in cellular lipid homeostasis. Involved in the plasma clearance of chylomicron remnants and activated LRPAP1 (alpha 2-macroglobulin), as well as the local metabolism of complexes between plasminogen activators and their endogenous inhibitors. May modulate cellular events, such as APP metabolism, kinase-dependent intracellular signaling, neuronal calcium signaling as well as neurotransmission.^[1] ^[2] ^[3] ^[4] ^[5] Functions as a receptor for Pseudomonas aeruginosa exotoxin A.^[6] ^[7] ^[8] ^[9] ^[10]

Publication Abstract from PubMed

The low-density lipoprotein receptor-related protein (LRP) interacts with more than 30 ligands of different sizes and structures that can all be replaced by the receptor-associated protein (RAP). The double module of complement type repeats, CR56, of LRP binds many ligands including all three domains of RAP and alpha2-macroglobulin, which promotes the catabolism of the Abeta-peptide implicated in Alzheimer's disease. To understand the receptor-ligand cross-talk, the NMR structure of CR56 has been solved and ligand binding experiments with RAP domain 1 (RAPd1) have been performed. From chemical shift perturbations of both binding partners upon complex formation, a HADDOCK model of the complex between CR56 and RAPd1 has been obtained. The binding residues are similar to a common binding motif suggested from alpha2-macroglobulin binding studies and provide evidence for an understanding of their mutual cross-competition pattern. The present structural results convey a simultaneous description of both binding partners of an LRP-ligand complex and open a route to a broader understanding of the binding specificity of the LRP receptor, which may involve a general four-residue receptor-ligand recognition motif common to all LRP ligands. The present result may be beneficial in the design of antagonists of ligand binding to the LDL receptor family, and especially of drugs for treatment of Alzheimer's disease.
