Mitochondrial calcium uptake is vital for cell function, but imbalances can cause cell death. This chapter reviews mitochondrial calcium uptake, homeostasis, and the key components of the mitochondrial calcium uniporter complex.
Area of Science:
- Cellular Biology
- Mitochondrial Physiology
- Biochemistry
Background:
- Mitochondrial calcium (Ca2+) uptake plays a critical role in cellular functions.
- Dysregulation of mitochondrial Ca2+ homeostasis is implicated in various pathophysiological conditions and cell death.
- Understanding mitochondrial Ca2+ dynamics is essential for comprehending cell physiology.
Purpose of the Study:
- To review the diverse mechanisms of mitochondrial Ca2+ uptake.
- To elucidate the current understanding of mitochondrial Ca2+ homeostasis in health and disease.
- To focus on the molecular components, regulators, and pharmacology of the mitochondrial Ca2+ uniporter complex.
Main Methods:
- Literature review of mitochondrial Ca2+ uptake mechanisms.
- Analysis of current research on mitochondrial Ca2+ homeostasis.
- Detailed examination of the mitochondrial Ca2+ uniporter complex.
Main Results:
- Overview of various mitochondrial Ca2+ uptake pathways.
- Summary of the established knowledge on mitochondrial Ca2+ regulation.
- Identification of key molecular players within the mitochondrial Ca2+ uniporter complex.
Conclusions:
- Mitochondrial Ca2+ uptake is a tightly regulated process crucial for cellular viability.
- Imbalances in mitochondrial Ca2+ handling contribute to cellular dysfunction and death.
- Further research into the mitochondrial Ca2+ uniporter complex offers therapeutic potential.

Most of these mitochondrial proteins are encoded by the nucleus and imported to the mitochondria as unfolded or loosely folded precursors. Mitochondrial precursors...
Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
