K-2P channels are a family of cellular proteins that are essential for electrical signaling throughout the body. There are six K-2P channel subfamilies, consisting of 15 distinct mammalian genes. K-2P channels display a remarkable range of regulation by cellular, physical and pharmacologic agents, including protein kinases, intracellular Ca2+ changes in internal and external pH, anesthetic agents, heat, stretch and membrane deformers. The molecular and cellular mechanisms underlying this regulation are complex and cooperate at many different levels. Recent research has provided strong evidence that the spatiotemporal-specific expression of K-2P channels are determinants of physiologic selectivity and specificity. In recent years, knockout mice have been generated with inactivated K-2P channel genes. These animals shed new light on the contribution of K-2P channels to normal and abnormal physiology. In, this review, we summarize the published data on these mice to broaden the understanding of the role of K-2P channel activity. (C) 2008 Elsevier Ltd. All rights reserved.
