In this mini episode, Dr. Jonathan Bogan explains how insulin triggers the TUG protein to help move GLUT 4 transporter proteins from inside the cell to the cell membrane. There, they transport glucose from the bloodstream into the cell using facilitated diffusion. Tune in next week for the full-length interview. Hosted on Acast.

Dr. Dina Simkin is an Research Assistant Professor at Northwestern University's Feinberg School of Medicine whose research mainly focuses on how on how mutations in ion channel proteins contribute to pediatric epilepsy and neurodevelopmental disorders. Dr. Simkin earned her BS in Biochemistry, and then proceeded to earn PhDs in Neuroscience, Biophysics, and in Cellular and Molecular Pharmacology. She additionally completed post-graduate training in both the neurophysiology of aging and stem cell-derived neuronal models of epileptic channelopathy.
