SUSTAINED EXOCYTOSIS AFTER ACTION POTENTIAL-LIKE STIMULATION AT LOW FREQUENCIES IN MOUSE CHROMAFFIN CELLS DEPENDS ON A DYNAMIN-DEPENDENT FAST ENDOCYTOTIC PROCESS [PDF]
Under basal conditions the action potential firing rate of adrenal chromaffin cells is lower than 0.5 Hz. The maintenance of the secretory response at such frequencies requires a continuous replenishment of releasable vesicles.

Animal and plant cytokineses appear morphologically distinct. Recent studies, however, have revealed that these cellular processes have many things in common, including the requirement of co‐ordinated membrane trafficking and cytoskeletal dynamics. At the intersection of these two processes are the members of the dynamin family of ubiquitous eukaryotic

The dynamin superfamily comprises a growing assortment of multi-domain GTPases, found from bacteria to man, that are distinguished from typical GTPases of the Ras, Rab and G-protein families by their modular structure (Figure 1), relatively large size (>70 kDa), and low affinity for guanine nucleotides.

Energy and Dynamics of Caveolae Trafficking
Caveolae are 70–100 nm diameter plasma membrane invaginations found in abundance in adipocytes, endothelial cells, myocytes, and fibroblasts. Their bulb-shaped membrane domain is characterized and formed by specific lipid binding proteins including ...

Mutations in human dynamin block an intermediate stage in coated vesicle formation [PDF]
The role of human dynamin in receptor-mediated endocytosis was investigated by transient expression of GTP-binding domain mutants in mammalian cells. Using assays which detect intermediates in coated vesicle formation, the dynamin mutants were found to ...

Dynamin is a large GTPase that forms a helical collar at the neck of endocytic pits, and catalyzes membrane fission (Schmid and Frolov, 2011; Ferguson and De Camilli, 2012).

Cytoplasmic sharing through apical membrane remodeling
Multiple nuclei sharing a common cytoplasm are found in diverse tissues, organisms, and diseases. Yet, multinucleation remains a poorly understood biological property. Cytoplasm sharing invariably involves plasma membrane breaches.

Essential function of dynamin in the invasive properties and actin architecture of v-Src induced podosomes/invadosomes. [PDF]
The large GTPase dynamin plays a key role in endocytosis but is also localized at numerous actin rich sites. We investigated dynamin functions at podosomes/invadosomes, actin-based cellular adhesion structures implicated in tissue invasion.

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 ...

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.
