Dynamin family protein
WebOne such protein that directly participates in the fission reaction is the GTPase dynamin, the founding member of a family of GTPases that have diverse roles in membrane remodelling events throughout the cell (Figure 1). The role of dynamin in endocytosis has now been investigated for more than 20 years 5-8. WebThe dynamin family of large GTPases has been implicated in vesicle formation from both the plasma membrane and various intracellular membrane compartments. The dynamin-like protein DLP1, recently identified in mammalian tissues, has been shown to be more closely related to the yeast dynamin proteins …
