PGAM5 is an MFN2 phosphatase that plays an essential role in the regulation of mitochondrial dynamics

Cell Reports, 2023
Summary: Mitochondrial morphology is regulated by the post-translational modifications of the dynamin family GTPase proteins including mitofusin 1 (MFN1), MFN2, and dynamin-related protein 1 (DRP1).

The Charcot–Marie Tooth Disease Mutation R94Q in MFN2 Decreases ATP Production but Increases Mitochondrial Respiration under Conditions of Mild Oxidative Stress

Cells, 2019
Charcot−Marie tooth disease is a hereditary polyneuropathy caused by mutations in Mitofusin-2 (MFN2), a GTPase in the outer mitochondrial membrane involved in the regulation of mitochondrial fusion and bioenergetics.

Mitofusin-2 in nucleus accumbens D2-MSNs regulates social dominance and neuronal function

Cell Reports, 2023
Summary: The nucleus accumbens (NAc) is a brain hub regulating motivated behaviors, including social competitiveness. Mitochondrial function in the NAc links anxiety with social competitiveness, and the mitochondrial fusion protein mitofusin 2 (Mfn2) in ...

Assessing the effects of mitofusin 2 deficiency in the adult heart using 3D electron tomography [PDF]

, 2017
The effects of mitofusin 2 (MFN2) deficiency, on mitochondrial morphology and the mitochondria-junctional sarcoplasmic reticulum (jSR) complex in the adult heart, have been previously investigated using 2D electron microscopy, an approach which is unable

Emerging functions of mammalian mitochondrial fusion and fission [PDF]

, 2005
Mitochondria provide a myriad of services to the cell, including energy production, calcium buffering and regulation of apoptosis. How these diverse functions are coordinated among the hundreds of mitochondria in a given cell is largely unknown, but is ...

Role of mitofusin 2 in the renal stress response. [PDF]

PLoS ONE, 2012
The role of mitofusin 2 (MFN2), a key regulator of mitochondrial morphology and function in the renal stress response is unknown. To assess its role, the MFN2 floxed gene was conditionally deleted in the kidney of mice (MFN2 cKO) by Pax2 promoter driven ...

The Role of Impaired Mitochondrial Dynamics in MFN2-Mediated Pathology

Frontiers in Cell and Developmental Biology, 2022
The Mitofusin 2 protein (MFN2), encoded by the MFN2 gene, was first described for its role in mediating mitochondrial fusion. However, MFN2 is now recognized to play additional roles in mitochondrial autophagy (mitophagy), mitochondrial motility, lipid ...

Evidence for the involvement of lipid rafts localized at the ER-mitochondria associated membranes in autophagosome formation [PDF]

, 2016
Mitochondria-associated membranes (MAMs) are subdomains of the endoplasmic reticulum (ER) that interact with mitochondria. This membrane scrambling between ER and mitochondria appears to play a critical role in the earliest steps of autophagy.

Mitofusin 2 Participates in Mitophagy and Mitochondrial Fusion Against Angiotensin II-Induced Cardiomyocyte Injury

Frontiers in Physiology, 2019
BackgroundMitochondrial dynamics play a critical role in mitochondrial function. The mitofusin 2 (MFN2) gene encodes a mitochondrial membrane protein that participates in mitochondrial fusion to maintain and operate the mitochondrial network.

Mitofusin-2 Negatively Regulates Melanogenesis by Modulating Mitochondrial ROS Generation

Cells, 2022
Inter-organellar communication is emerging as one of the most crucial regulators of cellular physiology. One of the key regulators of inter-organellar communication is Mitofusin-2 (MFN2).
