Title: TMBIM-mediated Ca 2+ homeostasis and cell death

Abstract

Ca 2+ is a ubiquitous intracellular messenger that regulates numerous physiological activities in humans, animals, plants, and bacteria. Cytosolic Ca 2+ is kept at a low level, but subcellular organelles such as the endoplasmic reticulum (ER) and Golgi Apparatus maintain high-concentration Ca 2+ stores. Under resting conditions, store Ca 2+ homeostasis is dynamically regulated to equilibrate between active Ca 2+ uptake and passive Ca 2+ leak processes. The evolutionarily conserved Transmembrane BAX Inhibitor-1 Motif-containing (TMBIM) proteins mediate Ca 2+ homeostasis and cell death. This review focuses on recent advances in functional and structural analysis of TMBIM proteins in regulation of the two related functions. The roles of TMBIM proteins in pathogen infection and cancer are also discussed with prospects for treatment.
