The Functional Impact of Mitochondrial Structure Across Subcellular Scales

open access: yesFrontiers in Physiology, 2020
Mitochondria are key determinants of cellular health. However, the functional role of mitochondria varies from cell to cell depending on the relative demands for energy distribution, metabolite biosynthesis, and/or signaling.

Consequences of Folding the Mitochondrial Inner Membrane

open access: yesFrontiers in Physiology, 2020
A fundamental first step in the evolution of eukaryotes was infolding of the chemiosmotic membrane of the endosymbiont. This allowed the proto-eukaryote to amplify ATP generation while constraining the volume dedicated to energy production.

Mitochondrial Cristae Architecture and Functions: Lessons from Minimal Model Systems

open access: yesMembranes, 2021
Mitochondria are known as the powerhouse of eukaryotic cells. Energy production occurs in specific dynamic membrane invaginations in the inner mitochondrial membrane called cristae.

Pathways shaping the mitochondrial inner membrane

open access: yesOpen Biology, 2021
Mitochondria are complex organelles with two membranes. Their architecture is determined by characteristic folds of the inner membrane, termed cristae.

Why does a mitochondrion need its individual cristae to be functionally autonomous?

open access: yesMolecular & Cellular Oncology, 2020
We demonstrated that individual cristae in one mitochondrion function as autonomous electrochemical units, with this autonomy being maintained by cristae junction modulators.

CARD19 Interacts with Mitochondrial Contact Site and Cristae Organizing System Constituent Proteins and Regulates Cristae Morphology

open access: yesCells, 2022
CARD19 is a mitochondrial protein of unknown function. While CARD19 was originally reported to regulate TCR-dependent NF-κB activation via interaction with BCL10, this function is not recapitulated ex vivo in primary murine CD8+ T cells.

Mitochondrial Membrane Dynamics—Functional Positioning of OPA1

open access: yesAntioxidants, 2018
The maintenance of mitochondrial energetics requires the proper regulation of mitochondrial morphology, and vice versa. Mitochondrial dynamins control mitochondrial morphology by mediating fission and fusion.

Structural Analysis of Mitochondria in Cardiomyocytes: Insights into Bioenergetics and Membrane Remodeling

open access: yesCurrent Issues in Molecular Biology, 2023
Mitochondria in mammalian cardiomyocytes display considerable structural heterogeneity, the significance of which is not currently understood. We use electron microscopic tomography to analyze a dataset of 68 mitochondrial subvolumes to look for ...

The Yin & Yang of Mitochondrial Architecture - Interplay of MICOS and F1Fo-ATP synthase in cristae formation

open access: yesMicrobial Cell, 2017
Oxidative phosphorylation takes place at specialized compartments of the inner mitochondrial membrane, the cristae. The elaborate ultrastructure of cristae membranes enables efficient chemi-osmotic coupling of respiratory chain and F1Fo-ATP synthase ...
