WebJan 18, 2024 · Dynamin, a 100-kDa large GTPase and mechanochemical enzyme, is recruited post clathrin coated vesicle formation and is critical to vesicle scission and ultimately recycling of the clathrin coated pits (Robinson et al., 1987; Shpetner and Vallee, 1989; Popova et al., 2013 ). Dynamin itself is a 96 kDa enzyme, and was first isolated when researchers were attempting to isolate new microtubule-based motors from the bovine brain. Dynamin has been extensively studied in the context of clathrin-coated vesicle budding from the cell membrane. Beginning from the N-terminus, Dynamin consists of a GTPase domain connected to a helical stalk domain via a flexibl…
