2. Receptors of Tyrosine
Popularly refer to as, Receptor Tyrosine Kinases (RTKs)
Receptors are molecules on cell membrane that binds to specific
substance and causes a specific effect on cell.
Tyrosine is an Amino acid
Kinase: Enzyme that catalyses the tranfer of phosphate groups.
3. Receptor Tyrosine kinase (RTK) is a catalystic receptor with inbuilt enzyme
activity.
Most are trans membrane proteins,they have a ligand (signal) binding
domain on extracellular end and Tyrosine Kinase domain in intracellular
end.
Examples, it act as receptor for
Insulin
