Study Notes
Receptor Tyrosine Kinases
- Receptor tyrosine kinases (RTKs) are a type of receptor that has inbuilt enzymatic activity.
- The ligand-binding domain in RTKs is located on the extracellular side.
- RTKs can bind to various growth factors, including epidermal growth factor (EGF), platelet-derived growth factor (PDGF), and fibroblast growth factor (FGF).
- RTKs have a specific structure, consisting of an extracellular ligand-binding domain, a transmembrane domain, and an intracellular tyrosine kinase domain.
- The tyrosine residues in RTKs are phosphorylated upon ligand binding, leading to the activation of downstream signaling pathways.
- The enzymatic activity of RTKs is called tyrosine kinase activity.
- RTKs are a type of catalytic receptor, which means they have inbuilt enzymatic activity.
