The low-density lipoprotein receptor mediates cholesterol homeostasis through endocytosis of lipoproteins. It discharges its ligand in the endosome at pH < 6. In the crystal structure at pH = 5.3, the ligand-binding domain (modules R2 to R7) folds back as an arc over the epidermal growth factor precursor homology domain (the modules A, B, β propeller, and C). The modules R4 and R5, which are critical for lipoprotein binding, associate with the β propeller via their calcium-binding loop. We…

Mechanism of Low Density Lipoprotein (LDL) Release in the Endosome
- Biology, ChemistryJournal of Biological Chemistry
- 2008
The temperature and calcium concentration dependence of LR5 stability clearly indicate that under endosomal conditions the unfolded conformation of the repeat is largely dominant, and a new mechanism for LDL release in the endosome is proposed in which calcium depletion and decreased stability at acidic pH drives LR5 unfolding, which triggers LDL release from the receptor.

The focus of the current review is on biochemical and structural studies of the LDLR and its ligands, emphasizing how structural features of the receptor dictate the binding of low-density lipoprotein (LDL) and beta-migrating forms of very low- density lipop protein (beta-VLDL), how the receptor releases bound ligands at low pH, and how the cytoplasmic tail of the HDLR interfaces with the endocytic machinery.

The studies show that the interface between the ligand binding domain and the EGF-precursor homology domain seen at acidic pH buries residues mediating both LDL binding and release, consistent with an alternative model of LDL-R whereby multiple modules of the extracellular domain interact with LDL at neutral pH.
LDL receptor/lipoprotein recognition: endosomal weakening of ApoB and ApoE binding to the convex face of the LR5 repeat
- Biology, ChemistryThe FEBS journal
- 2014
Endosomal conditions favour dissociation of LDLR/lipoprotein complexes regardless of whether active displacement of bound lipoproteins by the β‐propeller in LDLR takes place, and the multiple ApoE copies in β‐VLDLs, suggest that LDLR chelates lipoproteinins and enhances complex affinity by using more than one LR.

The three-dimensional structure of the human LDL receptor has been determined by two-dimensional NMR spectroscopy and shown to consist of a beta-hairpin structure, followed by a series of beta turns, which may represent a structural paradigm both for the other modules in the LDL receptor and for the homologous domains of several other proteins.
