Cadherins are a type of protein that play a crucial role in cell adhesion, helping cells stick together to form tissues. They are essential for maintaining the structure and integrity of tissues in organisms, including humans. Cadherins function by binding to similar cadherin molecules on adjacent cells, creating strong connections that are vital for tissue formation and stability. These proteins are involved in various biological processes, such as embryonic development and wound healing. Different types of cadherins exist, each with specific functions and locations in the body. Their proper functioning is important for overall health, and disruptions in cadherin activity can lead to diseases, including cancer.
