Ion channel-linked (ionotropic) receptors

These receptors are typically the targets of fast neurotransmitters such as acetylcholine (nicotinic) and GABA; activation of these receptors results in changes in ion movement across a membrane.

G protein-linked (metabotropic) receptors

This is the largest family of receptors and includes the receptors for several hormones and slow transmitters(dopamine, metabotropic glutamate). They are composed of seven transmembrane alpha helices. The loops connecting the alpha helices form extracellular and intracellular domains. The binding-site for larger peptide ligands is usually located in the extracellular domain whereas the binding site for smaller non-peptide ligands is often located between the seven alpha helices and one extracellular loop. These receptors are coupled to different intracellular effector systems via G proteins

Kinase-linked, enzyme-linked and related receptors

Receptor tyrosine kinases

Receptor tyrosine kinases (RTKs) are part of the larger family of protein tyrosine kinases. They are the high-affinity cell surface receptors for many polypeptide growth factors, cytokines, and hormones. Approximately 20 different RTK classes have been identified.^[2]

• RTK class I Epidermal Growth Factor Receptor family
• RTK class II Insulin receptor family
• RTK class III Platelet-derived growth factor receptor family
• RTK class IV Vascular Endothelial Growth Factor Receptor family
• RTK class V Fibroblast growth factor receptor family
• RTK class VIII Hepatocyte growth factor receptor family
• RTK class IX Ephrin receptor family
• RTK class XIII Epithelial discoidin domain-containing receptor (DDR receptor) family
