Ligand Binding
VLDLR binds compounds containing apolipoprotein E (apoE). These ligands attach to the cysteine binding repeats in the N-terminus end. The difference in cysteine-rich repeats between the members of the LDL receptor family lead to the differences in binding affinity. VLDLR, in particular, binds VLDL and intermediate-density lipoprotein (IDL), but not LDL. This inability to bind LDL is due to VLDLR's incapability to bind apolipoprotein B (apoB), which is present in LDL.
