Mitochondrial protein homeostasis [PDF]
IUBMB Life, 2013 AbstractMitochondria use 800–1,500 proteins to perform their biological functions in the eukaryotic cells. Distinct transport and sorting mechanisms are responsible for the delivery of proteins to the correct location within mitochondria. Mitochondrial proteins undergo processing events and form functional assemblies.

Mitochondrial protein dysfunction in pathogenesis of neurological diseases
Frontiers in Molecular Neuroscience, 2022 Mitochondria are essential organelles for neuronal function and cell survival. Besides the well-known bioenergetics, additional mitochondrial roles in calcium signaling, lipid biogenesis, regulation of reactive oxygen species, and apoptosis are pivotal ...

Mitochondrial protein import [PDF]
Biochimica et Biophysica Acta (BBA) - Reviews on Biomembranes, 1989 Most mitochondrial proteins are synthesized as precursor proteins on cytosolic polysomes and are subsequently imported into mitochondria. Many precursors carry amino-terminal presequences which contain information for their targeting to mitochondria. In several cases, targeting and sorting information is also contained in non-amino-terminal portions of

Structural insight into mitochondrial β-barrel outer membrane protein biogenesis
Nature Communications, 2020 The Sorting and Assembly Machinery (SAM) complex folds beta-barrel proteins and inserts them into the mitochondrial outer membrane. Here authors report cryoEM structures of the SAM complex from Myceliophthora thermophila, which reveals a GST-like fold ...

Mitochondrial Redox Signaling and Oxidative Stress in Kidney Diseases
Biomolecules, 2021 Mitochondria are essential organelles in physiology and kidney diseases, because they produce cellular energy required to perform their function. During mitochondrial metabolism, reactive oxygen species (ROS) are produced.

IRE1 KNOCKDOWN MODIFIES THE GLUTAMINE AND GLUCOSE DEPRIVATION EFFECT ON THE EXPRESSION OF NUCLEAR GENES ENCODING MITOCHONDRIAL PROTEINS IN U87 GLIOMA CELLS [PDF]
Biotechnologia Acta, 2016 We have studied the glucose and glutamine deprivation effect on the expression of nuclear genes encoding mitochondrial proteins in U87 glioma cells in relation to inhibition of inositol requiring enzyme-1 (IRE1).

RNAi-based gene silencing in primary mouse and human adipose tissues
Journal of Lipid Research, 2007 Cultured adipocyte cell lines are a model system widely used to study adipose function, but they exhibit significant physiological differences compared with primary cells from adipose tissue.

Tom70-based transcriptional regulation of mitochondrial biogenesis and aging
eLife, 2022 Mitochondrial biogenesis has two major steps: the transcriptional activation of nuclear genome-encoded mitochondrial proteins and the import of nascent mitochondrial proteins that are synthesized in the cytosol.

ER targeting of non-imported mitochondrial carrier proteins is dependent on the GET pathway
Life Science Alliance, 2021 The GET pathway is required to target non-imported mitochondrial carrier proteins to the endoplasmic reticulum, which prevents their deposition into Hsp42-dependent protein foci.
