Triple

Target class: receptor tyrosine kinase
Context triple: [HER2 receptor, instanceOf, receptor tyrosine kinase]

• A. G protein–coupled receptor
  A G protein–coupled receptor is a membrane-spanning protein that detects extracellular signals and activates intracellular G proteins to trigger specific cellular responses.
• B. cannabinoid receptor
  A cannabinoid receptor is a cell-surface G protein–coupled receptor that binds endogenous, plant-derived, or synthetic cannabinoids to modulate processes such as pain perception, appetite, mood, and immune function.
• C. Bruton tyrosine kinase inhibitor
  A Bruton tyrosine kinase inhibitor is a targeted small-molecule drug that blocks BTK signaling in B cells to disrupt pathways critical for their activation, proliferation, and survival, primarily used in the treatment of certain B-cell malignancies and autoimmune diseases.
• D. vascular endothelial growth factor inhibitor
  A vascular endothelial growth factor inhibitor is a drug or biological agent that blocks VEGF signaling to suppress the formation of new blood vessels, commonly used to treat cancers and certain eye diseases.
• E. cluster of differentiation antigen
  A cluster of differentiation antigen is a cell surface molecule used as a marker to identify and classify leukocyte subsets and other cell types, often serving functional roles in cell signaling and immune responses.
• F. None of above. chosen
