Wnt proteins are a group of signaling molecules that play a crucial role in cell communication and development. They are involved in various biological processes, including cell proliferation, differentiation, and migration. Wnt proteins bind to specific receptors on the surface of cells, initiating a cascade of events that influence gene expression and cellular behavior. These proteins are essential for embryonic development and tissue homeostasis in adults. Dysregulation of Wnt signaling has been linked to several diseases, including cancer and degenerative disorders. Understanding Wnt proteins and their pathways is important for developing potential therapeutic strategies.
