Connexin 26 is a protein that forms channels in cell membranes, allowing communication between adjacent cells. It is crucial for maintaining the function of various tissues, particularly in the inner ear and skin. Mutations in the gene that encodes Connexin 26 can lead to hearing loss and skin disorders. This protein is part of a larger family known as connexins, which play a vital role in cell signaling and homeostasis. Connexin 26 specifically helps in the transport of ions and small molecules, contributing to the overall health and function of tissues throughout the body.
