Receptor Tyrosine Kinases

Receptor tyrosine kinases (RTKs) are special proteins found on the surface of cells. They act like antennas, receiving signals from outside the cell, such as growth factors. When these signals attach to the RTKs, they activate the proteins, triggering a series of chemical reactions inside the cell. This process helps the cell grow, divide, and respond to its environment. RTKs are important in many biological processes, and their malfunction can lead to diseases, including cancer. Understanding RTKs is vital for developing targeted therapies in medicine.
