Notch receptors are a type of protein found on the surface of cells that play a crucial role in cell communication and development. They are part of the Notch signaling pathway, which helps regulate various processes such as cell differentiation, proliferation, and apoptosis. When a Notch receptor binds to its ligand on a neighboring cell, it triggers a series of events that influence the behavior of the receiving cell. These receptors are essential in many biological processes, including embryonic development and tissue homeostasis. Abnormal Notch signaling has been linked to various diseases, including certain types of cancer and neurodegenerative disorders. Understanding Notch receptors can provide insights into potential therapeutic targets for these conditions.
