OPA1 disease alleles causing dominant optic atrophy have defects in cardiolipin-stimulated GTP hydrolysis and membrane tubulation [PDF]
The dynamin-related GTPase OPA1 is mutated in autosomal dominant optic atrophy (DOA) (Kjer type), an inherited neuropathy of the retinal ganglion cells.

Loss of Mfn2 results in progressive, retrograde degeneration of dopaminergic neurons in the nigrostriatal circuit [PDF]
Mitochondria continually undergo fusion and fission, and these dynamic processes play a major role in regulating mitochondrial function. Studies of several genes associated with familial Parkinson's disease (PD) have implicated aberrant mitochondrial ...

Mitophagy: Mitofusin Recruits a Mitochondrial Killer [PDF]
Parkin is a cytosolic ubiquitin ligase that translocates to damaged mitochondria and promotes their degradation. Recent work demonstrates that a phosphorylated form of the mitochondrial fusion protein Mitofusin 2 serves as a receptor for Parkin translocation to damaged mitochondria.

Mitofusin 1 and mitofusin 2 are ubiquitinated in a PINK1/parkin-dependent manner upon induction of mitophagy [PDF]
Mitochondrial dysfunction and perturbed degradation of proteins have been implicated in Parkinson's disease (PD) pathogenesis. Mutations in the Parkin and PINK1 genes are a cause of familial PD. PINK1 is a putative kinase associated with mitochondria, and loss of PINK1 expression leads to mitochondrial dysfunction, which increases with time.

Mitofusin 2 ablation increases endoplasmic reticulum–mitochondria coupling [PDF]
Significance The privileged interrelationship between mitochondria and the endoplasmic reticulum (ER) plays a key role in a variety of physiological functions, from lipid metabolism to Ca 2+ signalling, and its modulation influences apoptotic susceptibility, mitophagy, and ...

Structural basis for membrane tethering by a bacterial dynamin-like pair
Dynamin-like proteins (DLPs) such as the mitofusins form homotypic and heterotypic oligomers that bridge and fuse opposing membranes. Here, Liu, Noel and Low present the crystal structure of a bacterial DLP heterotypic pair, providing insights into the ...
