Elucidation of clathrin-mediated endocytosis in tetrahymena reveals an evolutionarily convergent recruitment of dynamin. [PDF]
Ciliates, although single-celled organisms, contain numerous subcellular structures and pathways usually associated with metazoans. How this cell biological complexity relates to the evolution of molecular elements is unclear, because features in these ...

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.

Dynamin recruitment and membrane scission at the neck of a clathrin-coated pit [PDF]
Dynamin, the GTPase required for clathrin-mediated endocytosis, is recruited to clathrin-coated pits in two sequential phases. The first is associated with coated pit maturation; the second, with fission of the membrane neck of a coated pit.

Phosphorylation of dynamin by ERK2 inhibits the dynamin‐microtubule interaction [PDF]
In the present study we show that purified bovine brain dynamin can be phosphorylated by MAP kinase, ERK2, with a stoichiometry of 1 mol phosphate/mol dynamin. The phosphorylated serine residue is located within the C‐terminal 10 kDa of dynamin. Dynamin I phosphorylated by ERK2 can be specifically dephosphorylated by calcineurin but not by protein ...

Mitochondrial Membrane Dynamics—Functional Positioning of OPA1
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.

Dynamin 1 is required for memory formation. [PDF]
Dynamin 1-3 isoforms are known to be involved in endocytotic processes occurring during synaptic transmission. No data has directly linked dynamins yet with normal animal behavior.

Dynamin as a Mover and Pincher during Cell Migration and Invasion [PDF]
The large GTPase dynamin, long known for its role in endocytosis, has most recently been implicated as a facilitator of cell migration and invasion. Recent observations link dynamin to the cycle of membrane expansion and retraction essential for cell ...

Domain interactions within Fzo1 oligomers are essential for mitochondrial fusion [PDF]
Mitofusins are conserved GTPases essential for the fusion of mitochondria. These mitochondrial outer membrane proteins contain a GTPase domain and two or three regions with hydrophobic heptad repeats, but little is known about how these domains interact ...

Dynamin Subunit Interactions Revealed [PDF]
Dynamin family members are large GTPases that assemble into multimeric spirals. These spirals promote membrane fission or fusion, or they inhibit processes such as viral replication. Two new studies by Chappie et al. and Gao et al. in a recent issue of Nature identify interactions between subunits of dynamin spirals, advancing mechanistic understanding

Smed-dynA-1 is a planarian nervous system specific dynamin 1 homolog required for normal locomotion
Dynamins are GTPases that are required for separation of vesicles from the plasma membrane and thus are key regulators of endocytosis in eukaryotic cells. This role for dynamin proteins is especially crucial for the proper function of neurons, where they
