WebReceptor tyrosine kinases (RTK) are a relatively small family of integral membrane receptors. However, RTKs comprise nodes at the center of vastly complex signaling networks involving hundreds of signaling proteins. These signaling networks have essential functions in virtually all aspects of animal cell growth, development, and differentiation.
