Dynamin and endocytosis
WebJun 13, 1996 · Dynamin is a neuronal phosphoprotein and a GTPase enzyme which mediates late stages of endocytosis in both neural and non-neural cells. Current knowledge about dynamin is reviewed with particular emphasis on its structure and regulation with respect to phosphorylation, protein-protein interactions and phospholipid binding. WebOct 1, 2014 · Dynamin is a large GTPase that mediates plasma membrane fission during clathrin-mediated endocytosis. Dynamin assembles into polymers on the necks of …
Dynamin and endocytosis
Did you know?
WebDynamin is a protein required for vesicle formation during synaptic vesicle endocytosis (SVE) and for clathrin-mediated endocytosis. It is part of a family of large guanosine triphosphatases (GTPases), including classical dynamins, dynamin-like protein, optic atrophy 1 (OPA1), and mitofusin. Dynamin readily self-assembles into rings and helices ...

This large GTPase controls the fission reaction (reviewed in Sever et al. 2000). Some observations link dynamin to the actin cytoskeleton.
WebMar 12, 2024 · CLIC/GEEC endocytosis appears to be a constitutive process (that is, a continuous endocytic uptake mechanism independent of receptor–ligand interactions) and is clathrin and dynamin independent. WebDynamin 1 mediates the majority of synaptic vesicle endocytosis (SVE), particularly during a depolarization stimulus (Anggono and Robinson, 2009; Clayton et al., 2009) where dynamin 1 and several other endocytic proteins are constitutively phosphorylated in resting synapses and upon nerve stimulation.

WebSep 16, 2016 · Similarly to clathrin mediated endocytosis, dynamin is also required for scission and internalization of caveolae (Rewatkar et al., 2015). Although the speed of caveolae internalization is around five times slower than that of clathrin mediated endocytosis, the efficiency of cargo delivery into the cytosol is much higher (Ritter et al., … inap wildfireWebOct 13, 2014 · Using an inducible knockout mouse model to generate dynamin 1- and 2-deficient primary osteoclast precursors and myoblasts, we found that fusion of both cell … in a synchronous motorWebDynamin I interacts with multiple proteins in the nerve terminal, including SH3 domain-containing proteins such as amphiphysin and potentially with other proteins … inap social inap red socialWebAug 1, 2002 · Beyond dynamin's role in endocytosis.
