Mark’s research focuses on the 29-amino-acid endocrine peptide glucagon. Glucagon is responsible for elevating blood glucose through stimulation of its cognate, G-protein coupled receptor, the glucagon receptor (GCGR). As the worldwide prevalence of diabetes is increasing, pharmacological intervention of glucagon’s effect as a novel treatment for attaining prolonged glucose homeostasis in diabetic patients is receiving greater attention. By combining molecular biology techniques with characterisation via native mass spectrometry Mark hopes to better understand glucagon peptide-receptor interactions, and how other membrane components (for example, lipids, G-proteins, and accessory proteins) allosterically influence binding properties.
Mark graduated from the University of California San Diego and completed his PhD studies at the University of Arizona. He joined the Robinson group in 2017.
