Research Abstract

The Rab family of small G proteins, which consists of more than 60 different members in mammalian cells, is a key regulator in membrane trafficking. Since each member recognizes distinct subsets on intracellular membranes, this family may contribute to temporal and spatial regulation of signal transduction in various cellular functions. In this project, we analyzed the functions of Rab proteins in synaptic formation and following maturation.
