BBB "extra" seminar: Margaret Stratton
Unraveling the complexity of CaMKII activation
Monday, December 10, 14.30 - NB! Day
Department of Biochemistry and Molecular Biology, University of Massachusetts Amherst, MA, USA
Ca2+-calmodulin dependent protein kinase II (CaMKII) is a crucial oligomeric enzyme in neuronal and cardiac signaling, fertilization and immunity. Work in the Stratton lab is focused on understanding the role of this fascinating enzyme in different tissues. We have used RNA sequencing to determine which transcripts are present and we are characterizing these different variants in terms of their activation profiles. To facilitate our studies in cells, we have developed a novel, substrate-based, genetically-encoded sensor for CaMKII activity, FRESCA (FRET-based Sensor for CaMKII Activity), which has allowed us to monitor CaMKII activity in live cells under various conditions. We hope that by gaining an understanding of CaMKII in vitro and in cells, we will be able to better understand medical conditions in which it is implicated, such as memory deficiencies and infertility.
