Role of the Rab5 Guanine Nucleotide Exchange Factor, Rme-6, in the Regulation of Clathrin-Coated Vesicle Uncoating
Clathrin-coated pits are major ports of entry into eukaryotic cells. Following scission of clathrin-coated pits to form coated vesicles, the peripheral membrane proteins that form the coat need to be removed. Here we describe an assay that provides a measure of the extent of clathrin coat uncoating in intact cells. This assay has been used to investigate rab5-dependent modulation of uncoating. Specifically, it has been used to identify functional differences between rab5 guanine nucleotide exchange factors.
