Mg2+ Homeostasis: The Mg2+nificent TRPM Chanzymes
TRPM6 and TRPM7 are distinct from all other ion channels in that they are composed of linked channel and protein kinase domains. Recent studies demonstrate that these 'chanzymes' are essential for Mg(2+) homeostasis, which is critical for human health and cell viability.
متن کاملMg2+ homeostasis: the balancing act of TRPM6.
PURPOSE OF REVIEW The tight control of blood magnesium (Mg) levels is of central importance for numerous physiological processes. A persistent low Mg status (hypomagnesemia) is associated with severe health risks and is involved in the pathogenesis of type 2 diabetes mellitus, osteoporosis, asthma, and heart and vascular diseases. The current view has expanded significantly as a result of the i...
متن کاملMolecular components of vertebrate Mg2+-homeostasis regulation.
Over the past decades, the clinical relevance and biological significance of Mg2+ have been thoroughly documented. Although multiple Mg2+-transport pathways have been biophysically characterized, the molecular identity of the postulated components of Mg2+-homeostasis regulation in vertebrates remain undefined. Recent advances in the fields of genetics, genomics and proteomics, and novel technol...
متن کاملChronic EtOH administration alters liver Mg2+ homeostasis.
Ethanol (EtOH) administration to rats for 4 wk markedly decreased Mg(2+) content in several tissues, including liver. Total cellular Mg(2+) accounted for 26.8 +/- 2.4 vs. 36.0 +/- 1.4 nmol Mg(2+)/mg protein in hepatocytes from EtOH-fed and control rats, respectively, and paralleled a 13% decrease in cellular ATP content. Stimulation of alpha(1)- or beta-adrenergic receptor or acute EtOH adminis...
متن کاملEvolution of a Bacterial Regulon Controlling Virulence and Mg2+ Homeostasis
Related organisms typically rely on orthologous regulatory proteins to respond to a given signal. However, the extent to which (or even if) the targets of shared regulatory proteins are maintained across species has remained largely unknown. This question is of particular significance in bacteria due to the widespread effects of horizontal gene transfer. Here, we address this question by invest...
