| Scientific Background: | The Rab family of GTP-binding proteins are members of the Ras superfamily of small G proteins, and participate in multiple steps of the membrane trafficking. Rab3A participates in the fusion of synaptic vesicles during neurotransmitter release, a process regulated by GDP/GDP exchange cofactors such as GAP, GDI, GRF, and rabphilin. Rab4 regulates recycling of proteins from the early endosome to the surface of many cell types, regulating glucose transporter and transferrin receptor cell surface localization. Rab5 regulates the fusion of plasma membrane-derived clathrin-coated vesicles with early endosomes and homotypic fusion among early endosomes. |
