Multifunctional cell surface receptor that binds VLDL and transports it into cells by endocytosis and therefore plays an important role in energy metabolism. Binds also to a wide range of other molecules including Reelin/RELN or apolipoprotein E/APOE-containing ligands as well as clusterin/CLU. In the off-state of the pathway, forms homooligomers or heterooligomers with LRP8. Upon binding to ligands, homooligomers are rearranged to higher order receptor clusters that transmit the extracellular RELN signal to intracellular signaling processes by binding to DAB1 (By similarity). This interaction results in phosphorylation of DAB1 leading to the ultimate cell responses required for the correct positioning of newly generated neurons. Later, mediates a stop signal for migrating neurons, preventing them from entering the marginal zone (By similarity). Homooligomer. Binds to the extracellular matrix protein Reelin/RELN. Interacts with LRP8 (By similarity). Interacts with LDLRAP1 (By similarity). Interacts with SNX17 (By similarity). Interacts with DAB1. Interacts with PCSK9. Interacts with PAFAH1B3 and PAFAH1B2, the catalytic complex of (PAF-AH (I)) heterotetrameric enzyme; these interactions may modulate the Reelin pathway. Interacts with STX5; this interaction mediates VLDLR translocation from the endoplasmic reticulum to the plasma membrane. Interacts with CLU (By similarity). Abundant in heart, muscle, and adipose tissue. Ubiquitinated at Lys-839 by MYLIP leading to degradation.
