Triple

Target class: glycoprotein
Context triple: [CD46, instanceOf, glycoprotein]

• A. viral surface glycoprotein
  A viral surface glycoprotein is a membrane-anchored protein with attached carbohydrate chains that protrudes from the virus surface and mediates host cell recognition, attachment, and entry, while often serving as a key target for the host immune response.
• B. protein chosen
  A protein is a large, complex biological molecule composed of one or more chains of amino acids that fold into specific three-dimensional structures to perform diverse structural, catalytic, signaling, and regulatory functions in living organisms.
• C. heterotrimeric G protein
  A heterotrimeric G protein is a membrane-associated signaling protein complex composed of three distinct subunits (α, β, and γ) that transduces signals from activated G protein–coupled receptors to intracellular effector pathways by cycling between GDP-bound inactive and GTP-bound active states.
• D. 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.
• E. biomolecule
  A biomolecule is any organic molecule produced by living organisms that plays a role in their structure, function, or regulation, such as proteins, nucleic acids, carbohydrates, and lipids.
• F. None of above.
