Abstract
Calcium (Ca 2+ ) is a second messenger essential for cellular homeostasis. Inside the cell, Ca 2+ is compartmentalized and exchanged among organelles in response to both external and internal stimuli. Mitochondria‐associated membranes (MAMs) provide a platform for proteins and channels involved in Ca 2+ transfer between the endoplasmic reticulum (ER) and mitochondria. Deregulated Ca 2+ signaling and proteins regulating ER–mitochondria interactions have been linked to liver diseases and intensively investigated in recent years. In this review, we summarize the role of MAM‐resident proteins in Ca 2+ transfer and their association with different liver diseases.
