Connexin 32 is a protein that forms gap junctions, which are channels that allow communication between adjacent cells. It is primarily found in the liver, peripheral nervous system, and other tissues. These channels enable the transfer of ions and small molecules, facilitating cellular signaling and maintaining tissue homeostasis. Mutations in the Connexin 32 gene can lead to various health issues, including Charcot-Marie-Tooth disease, a hereditary neuropathy that affects the peripheral nerves. Understanding the function of Connexin 32 is crucial for developing potential therapies for conditions related to gap junction dysfunction.
