Dynamin-Like Protein B of Dictyostelium Contributes to Cytokinesis Cooperatively with Other Dynamins [PDF]

Cells, 2019
Dynamin is a large GTPase responsible for diverse cellular processes, such as endocytosis, division of organelles, and cytokinesis. The social amoebozoan, Dictyostelium discoideum, has five dynamin-like proteins: dymA, dymB, dlpA, dlpB, and dlpC.

Monitoring of dynamin during the Toxoplasma gondii cell cycle [PDF]

Pathogens and Disease, 2016
The obligate intracellular protozoan parasite Toxoplasma gondii actively invades virtually all warm-blooded nucleated cells. This process results in a non-fusogenic vacuole, inside which the parasites replicate continuously until egress signaling is ...

Inositol hexakisphosphate promotes dynamin I- mediated endocytosis [PDF]

Proceedings of the National Academy of Sciences, 2002
Membrane homeostasis is maintained by exocytosis and endocytosis. The molecular mechanisms regulating the interplay between these two processes are not clear. Inositol hexakisphosphate (InsP 6 ) is under metabolic control and serves as a signal in the pancreatic β cell stimulus-secretion coupling by increasing Ca

Dynamin inhibitor impairsToxoplasma gondiiinvasion [PDF]

FEMS Microbiology Letters, 2009
The protozoan parasite Toxoplasma gondii infects its host cells through an active mechanism. In this work, we obtained evidence that host cells also play a fundamental role during the infection process. We found that previous incubation of the host cells, but not the parasites, with Dynasore, a small molecule that inhibits dynamin GTPase activity ...

Syndapin I is the phosphorylation-regulated dynamin I partner in synaptic vesicle endocytosis [PDF]

Nature Neuroscience, 2006
Dynamin I is dephosphorylated at Ser-774 and Ser-778 during synaptic vesicle endocytosis (SVE) in nerve terminals. Phosphorylation was proposed to regulate the assembly of an endocytic protein complex with amphiphysin or endophilin. Instead, we found it recruits syndapin I for SVE and does not control amphiphysin or endophilin binding in rat ...

Nodal‐mediated epigenesis requires dynamin‐mediated endocytosis [PDF]

Developmental Dynamics, 2011
AbstractNodal proteins are diffusible morphogens that drive pattern formation via short‐range feedback activation coupled to long‐range Lefty‐mediated inhibition. In the sea urchin embryo, specification of the secondary (oral‐aboral) axis occurs via zygotic expression of nodal, which is localized to the prospective oral ectoderm at early blastula stage.

Nitric oxide regulates endocytosis by S -nitrosylation of dynamin [PDF]

Proceedings of the National Academy of Sciences, 2006
The GTPase dynamin regulates endocytic vesicle budding from the plasma membrane, but the molecular mechanisms involved remain incompletely understood. We report that dynamin, which interacts with NO synthase, is S -nitrosylated at a single cysteine residue (C607) after stimulation of the β 2 ...

Immature Stages of the Neotropical Butterfly,Dynamine agacles agacles [PDF]

Journal of Insect Science, 2012
The external morphology of the immature stages of Dynamine agacles agacles (Dalman, 1823) (Lepidoptera: Nymphalidae: Biblidinae) is described, including photos, drawings, and scanning electron micrographs. Data on the adult and larval behavior are given based on observations in the host plant Dalechampia triphylla Lam.

Dynamin as a Mover and Pincher during Cell Migration and Invasion [PDF]

, 2006
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 ...

Mutations in human dynamin block an intermediate stage in coated vesicle formation [PDF]

, 1993
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 ...
