Homodimeric intrinsic membrane proteins. Identification and modulation of interactions between mitochondrial transporter (carrier) subunits [PDF]
Biochemical and Biophysical Research Communications, 2010 Transporter (carrier) proteins of the inner mitochondrial membrane link metabolic pathways within the matrix and the cytosol with transport/exchange of metabolites and inorganic ions. Their strict control of these fluxes is required for oxidative phosphorylation.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Mitochondrial Dysfunction in Human Leukemic Stem/Progenitor Cells upon Loss of RAC2.
PLoS ONE, 2015 Leukemic stem cells (LSCs) reside within bone marrow niches that maintain their relatively quiescent state and convey resistance to conventional treatment. Many of the microenvironmental signals converge on RAC GTPases.

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Protein insertion into the inner membrane of mitochondria: routes and mechanisms
FEBS Open BioThe inner membrane of mitochondria contains hundreds of different integral membrane proteins. These proteins transport molecules into and out of the matrix, they carry out multifold catalytic reactions and they promote the biogenesis or degradation of ...

Interconnected roles of mitochondrial carrier proteins ANT, PiT, and UCPs in proton transport
Frontiers in Molecular BiosciencesIntroductionAdenine nucleotide translocase (ANT), phosphate translocase (PiT), and uncoupling proteins (UCPs), all integral to oxidative phosphorylation, are among the carrier proteins of the mitochondrial inner membrane (MIM).

Transport of proteins to the mitochondrial intermembrane space: the ‘sorting’ domain of the cytochrome c1 presequence is a stop-transfer sequence specific for the mitochondrial inner membrane. [PDF]
The EMBO Journal, 1987 The presequence of yeast cytochrome c1 (an inner membrane protein protruding into the intermembrane space) contains a matrix-targeting domain and an intramitochondrial sorting domain. This presequence transports attached subunit IV of cytochrome c oxidase into the intermembrane space (van Loon et al. (1987) EMBO J., 6, 2433-2439). In order to determine

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

The carboxyl-terminal two-thirds of the ADP/ATP carrier polypeptide contains sufficient information to direct translocation into mitochondria [PDF]
, 1987 The precursor of the mitochondrial inner membrane protein ADP/ATP carrier is cytoplasmically synthesized without an amino-terminal peptide extension. We constructed a truncated precursor lacking the 103 amino acids from the amino terminus (about a third ...

The Human SLC25A33 and SLC25A36 Genes of Solute Carrier Family 25 Encode Two Mitochondrial Pyrimidine Nucleotide Transporters [PDF]
, 2014 The human genome encodes 53 members of the solute carrier family 25 (SLC25), also called the mitochondrial carrier family, many of which have been shown to transport inorganic anions, amino acids, carboxylates, nucleotides, and coenzymes across the inner
