Introduction
TMEM16 proteins, discovered in 2008, are a group of ion channels that play a crucial role in various physiological processes. These proteins are encoded by ten different genes and are found in many tissues throughout the body. As ion channels, TMEM16 proteins facilitate the movement of ions across cellular membranes, thereby regulating important cellular functions such as electrical signaling and fluid secretion. Their presence and activity contribute to the proper functioning of organs and systems, including the nervous, respiratory, and gastrointestinal systems.
The discovery of TMEM16 proteins has provided an exciting avenue for the development of new drugs for a range of diseases. TMEM16 proteins are ion channels that play a critical role in a variety of physiological processes, including neurotransmitter release, smooth muscle contraction, and mucus secretion. The identification of drugs that can inhibit these proteins has the potential to treat a broad range of diseases, including cystic fibrosis, hypertension, and asthma.
Role of TMEM16 proteins in disease
The discovery of TMEM16 proteins has provided an exciting avenue for the development of new drugs for a range of diseases. In cystic fibrosis, for example, the defective CFTR protein leads to an increase in TMEM16A expression, which contributes to the buildup of mucus in the lungs. In hypertension, TMEM16A is upregulated in smooth muscle cells, contributing to vasoconstriction and increased blood pressure.
