N-cadherin is a type of protein that plays a crucial role in cell adhesion, helping cells stick together in tissues. It is primarily found in the nervous system, heart, and muscles, where it contributes to the formation and maintenance of structures like synapses and muscle fibers. This protein is part of the cadherin family, which are essential for the development and organization of tissues. N-cadherin interacts with other proteins to facilitate communication between cells, influencing processes such as cell migration, growth, and differentiation. Its proper function is vital for healthy tissue development and repair.
