Cx32 is a type of protein known as a gap junction protein, specifically a member of the connexin family. It plays a crucial role in cell communication by forming channels that allow ions and small molecules to pass between adjacent cells. This function is essential for maintaining tissue homeostasis and coordinating cellular activities. Mutations in the Cx32 gene can lead to various health issues, including Charcot-Marie-Tooth disease, a hereditary neuropathy that affects peripheral nerves. Understanding Cx32's structure and function is important for developing potential therapies for conditions related to gap junction dysfunction.
