Pro-diversity mitofusins [PDF]
The Journal of Cell Biology, 2007 Affirmative action groups would be proud of Mfn proteins. These fusion proteins work better with diverse partners, say Detmer and Chan (page [405][1]). The results might help explain why only certain neurons are susceptible in Charcot-Marie-Tooth disease 2A (CMT2A).

Burst mitofusin activation reverses neuromuscular dysfunction in murine CMT2A
eLife, 2020 Charcot–Marie-Tooth disease type 2A (CMT2A) is an untreatable childhood peripheral neuropathy caused by mutations of the mitochondrial fusion protein, mitofusin (MFN) 2.

Broad activation of the ubiquitin-proteasome system by Parkin is critical for mitophagy [PDF]
, 2011 Parkin, an E3 ubiquitin ligase implicated in Parkinson's disease, promotes degradation of dysfunctional mitochondria by autophagy. Using proteomic and cellular approaches, we show that upon translocation to mitochondria, Parkin activates the ubiquitin ...

HCT116 colorectal liver metastases exacerbate muscle wasting in a mouse model for the study of colorectal cancer cachexia [PDF]
, 2020 Colorectal cancer (CRC) is often accompanied by formation of liver metastases (LM) and skeletal muscle wasting, i.e. cachexia. Despite affecting the majority of CRC patients, cachexia remains underserved, understudied and uncured.

Mitofusins: Mighty Regulators of Metabolism [PDF]
Cell, 2013 Mitochondria are central regulators of cellular metabolism but how their function in a subset of cells affects whole-body energy balance is less understood. Two studies in this issue of Cell identify how diet-dependent modulation of mitochondrial fusion in specific neuronal circuits impact the metabolic status of an animal.

The INs and OUTs of mitofusins [PDF]
Journal of Cell Biology, 2018 Mitofusins are outer membrane proteins essential for mitochondrial fusion. Their accepted topology posits that both N and C termini face the cytoplasm. In this issue, Mattie et al. (2018. J. Cell Biol. https://doi.org/10.1083/jcb.201611194) demonstrate instead that their C termini reside in the intermembrane space. These findings call for a revision of

Endoplasmic Reticulum Stress and Mitochondrial Function in Airway Smooth Muscle
Frontiers in Cell and Developmental Biology, 2020 Inflammatory airway diseases such as asthma affect more than 300 million people world-wide. Inflammation triggers pathophysiology via such as tumor necrosis factor α (TNFα) and interleukins (e.g., IL-13).

Structure and function of bacterial dynamin-like proteins [PDF]
, 2012 Membrane dynamics are essential for numerous cellular processes in eukaryotic and prokaryotic cells. In eukaryotic cells, membrane fusion and fission are often catalyzed by large GTPases of the dynamin protein family. These proteins couple GTP hydrolysis

A mitofusin-dependent docking ring complex triggers mitochondrial fusion in vitro
eLife, 2016 Fusion of mitochondrial outer membranes is crucial for proper organelle function and involves large GTPases called mitofusins. The discrete steps that allow mitochondria to attach to one another and merge their outer membranes are unknown.

Mitochondrial dynamics–fusion, fission, movement, and mitophagy–in neurodegenerative diseases [PDF]
, 2009 Neurons are metabolically active cells with high energy demands at locations distant from the cell body. As a result, these cells are particularly dependent on mitochondrial function, as reflected by the observation that diseases of mitochondrial ...
