 who discovered the glucose transporter GLUT4

GLUT4

Glucose transporter type 4, also known as GLUT4, is a protein that in humans is encoded by the GLUT4 gene. GLUT4 is the insulin-regulated glucose transporter found in adipose tissues and striated muscle that is responsible for insulin-regulated glucose translocation into the cell...

. He has also been responsible for the molecular dissection of the intracellular trafficking pathways that regulate GLUT4 translocation to the cell surface, the topological mapping of the insulin signal transduction pathway, the creation of a method for studying in vivo metabolism in small animals, and the use of this method to gain insights into whole-animal fuel metabolism and homeostasis.

He is currently holds joint appointments at the Garvan Institute of Medical Research
