Research description: Dr. Crabtree’s group is interested in the role of signaling by Ca2+-calcineurin-NFAT and its regulation by the Dyrk1a kinase in the development and function of beta cells in the pancreas. They have isolated inhibitors of this pathway, made knock-out mice for each of the components and collaborated effectively with Seung Kim’s laboratory to explore the role of Calcineurin/NFAT/Dyrk1a in regulating the proliferation and function of adult beta cells. This work has had a powerful and sustained influence on studies in the fields of islet biology and diabetes research.
