Cadherin is a type of protein that plays a crucial role in cell adhesion, helping cells stick together to form tissues. These proteins are found in the membranes of cells and are essential for maintaining the structure and integrity of tissues in organisms. Cadherins are involved in various biological processes, including development, wound healing, and the maintenance of tissue architecture. There are several types of cadherins, each with specific functions and locations in the body. For example, E-cadherin is primarily found in epithelial tissues, while N-cadherin is more common in neural tissues. The proper functioning of cadherins is vital for normal cellular communication and tissue organization.
