Did you know?
WebThe GTPase dynamin is essential for CME (clathrin-mediated endocytosis), but its exact function and mechanism of action have been controversial. Here, we review findings that have led to the current models for dynamin function, either as a mechanochemical enzyme driving membrane fission or as a regu … 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 …
