Study Notes
- Ligands deliver signals for normal cell growth.
- Ligands can be growth factors, inhibitors, extracellular matrix components, or cell adhesion molecules.
- Receptors on cell surfaces transmit signals into the cell.
- Receptors often consist of three domains: extracellular ligand-binding, transmembrane, and intracellular.
- Tyrosine kinase is a receptor activated by ligand binding.
- Tyrosine kinase activates other proteins by phosphorylation.
- Normal cells respond to ligand binding by activating a cascade of signals.
- The nucleus is signaled to promote cell growth and division or stop growth.
- Cellular restraints on gene expression limit receptor production.
- Protein translation is also a factor in receptor production.
