WebNov 15, 2006 · Dynamin is a GTPase that plays a key role in the endocytic scission process in mammalian cells (Song and Schmid, 2003). Although dynamin relatives are present in yeast, there is no experimental support for a role for this family of proteins in endocytosis (Engqvist-Goldstein and Drubin, 2003). Alternatively, in the absence of amphiphysins ... WebFeb 15, 2000 · The effects of three mechanistically distinct inhibitors of clathrin-mediated endocytosis, MDC, Y231F/Y597F dynamin I, and β-arrestin 1 318–419, were determined. MDC inhibits clathrin-mediated endocytosis by stabilizing clathrin cages and has been shown to inhibit insulin-like growth factor-I as well as LPA-mediated ERK activation .
