Cell surface receptors are "proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behavior of the target cell (From Alberts, Molecular Biology of the Cell, 2nd ed, pp693-5). Cell surface receptors, unlike enzymes, do not chemically alter their ligands."[1][2] Examples are neurotransmitters and biogenic amine receptors.

Classification

Mechanistic classes include:[3]

  1. Protein-tyrosine kinase receptor
  2. Ion channel
  3. G-protein-coupled receptor
