WebThe results demonstrate that GPR15 internalisation is moderately dependent on GRKs and clathrin, and highly dependent on caveolin and dynamin. Moreover, a bystander arrestin recruitment assay showed that GPR15 recruits arrestin-3 to the cell membrane upon agonist stimulation, although GPR15 internalizes in an arrestin-independent manner. WebAfter clathrin and AP-2, dynamin was one of the first proteins found to participate in clathrin-mediated membrane budding. Dynamin contains an N-terminal GTPase domain, a PH domain that binds predominantly to …

WebJun 20, 2024 · Clathrin-mediated endocytosis (CME) is the major endocytic pathway in mammalian cells. It is responsible for the uptake of transmembrane receptors and transporters, for remodeling plasma membrane composition in response to environmental changes, and for regulating cell surface signaling. WebNov 1, 2024 · Dynamin as an important endocytosis-related protein has been extensively studied, especially in neurons (Antonny et al., 2016; Fan et al., 2016; Raimondi et al., 2011). However, the expression patterns of dynamin isoforms and their roles in clathrin-dependent endocytosis in non-neuronal cells are still incompletely understood.

WebApr 13, 2024 · In eukaryotes, dynamins and dynamin-related proteins (DRPs) are high–molecular weight GTPases responsible for mechanochemical fission of organelles or membranes. Of the six DRP subfamilies in Arabidopsis thaliana, AtDRP1 and AtDRP2 family members serve as endocytic accessory proteins in clathrin-mediated endocytosis. Most … WebDynamin (and Clathrin) also appears important for the formation of synaptic vesicles from the membranes that were retrieved by bulk endocytosis.
