Abstract: AbstractUsing various biochemical, pharmacological and molecular biological approaches, we have recently reported regulatory roles for Rac1, a small G-protein, in glucose-stimulated insulin secretion [GSIS]. However, little is understood with respect to localization of, and regulation by, specific regulatory factors of Rac1 in GSIS. Herein, we investigated regulatory roles for Tiam1, a specific nucleotide exchange factor [GEF] for Rac1, in GSIS in pancreatic β-cells. Western blot analysis indicated that Tiam…
