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]
- Protein-tyrosine kinase receptor. There are 90 tyrosine kinases, of which 58 are cell receptors that are divided into 20 subfamilies.[4] Examples include the insulin receptor, ErbB-1 receptor, and ErbB-2 receptor (Human Epidermal growth factor Receptor 2, HER2, HER-2).
- Ion channel
- G-protein-coupled receptor. Examples include adrenergic receptors, angiotensin receptors, bradykinin receptors, CCR5 receptor (used by HIV to infect cells), and opioid receptors.
