Dynamin is a GTPase protein that is essential for membrane fission during
clathrin-mediated endocytosis in eukaryotic cells. Dynasore is a GTPase inhibitor
that rapidly and reversibly inhibits dynamin activity, which prevents
endocytosis. However, comparison between cells treated with dynasore and RNA
interference of genes encoding dynamin, reveals evidence that dynasore reduces
labile cholesterol in the plasma membrane, and disrupts lipid raft organization,
in a dynamin-independent manner. To explore the role of dynamin it is important
to use multiple dynamin inhibitors, alongside the use of dynamin mutants and RNA
interference targeting genes encoding dynamin. On the other hand, dynasore
provides an interesting tool to explore the regulation of cholesterol in plasma
membranes.
