Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: LDL receptor | Statement: [APOE ε3 allele, proteinIsoformBindsReceptor, LDL receptor]

Target entity: LDL receptor
Context triple: [APOE ε3 allele, proteinIsoformBindsReceptor, LDL receptor]

• A. LDL receptor chosen
  The LDL receptor is a cell-surface protein that binds and internalizes low-density lipoprotein particles, playing a central role in cholesterol homeostasis and cardiovascular disease risk.
• B. NPC1L1 transporter
  The NPC1L1 transporter is an intestinal membrane protein that mediates cholesterol absorption from the gut and is inhibited by the lipid-lowering drug ezetimibe.
• C. Frizzled receptor
  Frizzled receptors are a family of G protein–coupled receptor-like proteins that serve as primary cell-surface receptors for Wnt signaling, regulating key processes in development and cell fate determination.
• D. LRP1
  LRP1 is a multifunctional endocytic and signaling receptor involved in lipid metabolism, clearance of extracellular molecules, and modulation of neuronal and vascular processes.
• E. Ldl
  Ldl is the official station code for Leiden Lammenschans railway station in the Netherlands.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.

  Indicates that a specific type of receptor is present at, or associated with, a particular effector site or effector cell.
• C. isoformNumber
  Indicates the specific variant index or identifier assigned to one isoform among multiple alternative forms of the same gene or protein.
• D. receptorSystem
