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. WebIn animal cells, the protein dynamin is involved in membrane scission during endocytosis, allowing invaginating vesicles to become internalised. Arabidopsis encodes two proteins …

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 … WebDec 20, 2012 · Briefly, they blocked EGFR endocytosis in HeLa cells with a pharmacologic inhibitor of dynamin, Dynasore, and assessed the generation of phosphospecific …
WebSep 4, 2000 · Dynamins have been a focus of the endocytosis research since it was demonstrated that the block of endocytosis in the shibire mutant of Drosophila is due to a mutation in dynamin. This large GTPase controls the fission reaction (reviewed in Sever et al. 2000). Some observations link dynamin to the actin cytoskeleton. WebAn extraordinary set of studies has recently established a physiological role for Arc protein in AMPA receptor endocytosis. First, biochemical assays revealed that Arc protein binds to two proteins (endophilin 3 and dynamin 2), which are involved in the endocytosis of membrane vesicles (Chowdhury et al., 2006). This binding occurs via separate ...

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.
Web8 minutes ago · Dynamin-related protein (Drp1), a large GTPase, has been found to play an implicit role in the process of mitochondrial fission by catalyzing membrane pinching and produces an action similar to vesicle endocytosis and peroxisomal fission.
WebThis gene encodes a member of the dynamin subfamily of GTP-binding proteins. The encoded protein possesses unique mechanochemical properties used to tubulate and sever membranes, and is involved in clathrin-mediated endocytosis and other vesicular trafficking processes.
