Endoplasmic Reticulum Calcium Homeostasis in Kidney Disease

Calcium (Ca2+) homeostasis is a crucial determinant of cellular function and survival. Endoplasmic reticulum (ER) acts as the largest intracellular Ca2+ store that maintains Ca2+ homeostasis through the ER Ca2+ uptake pump, sarco/ER –Ca2+ ATPase, ER Ca2+ release channels, inositol 1,4,5-trisphosphate receptor channel, ryanodine receptor, and Ca2+-binding proteins inside of the ER lumen. Alterations in ER homeostasis trigger ER Ca2+ depletion and ER stress, which have been associated with the development of a variety of diseas es.
