Cell and Developmental Biology. Calmodulin is the primary, essential calcium-binding protein of all eukaryotes and has changed little throughout evolution. It plays a fundamental role in a diverse number of biomedically-relevant events including chemotaxis, growth and differentiation. We study the proteins to which calmodulin binds and regulates, to further understand how it mediates these processes. Using the model eukaryotic amoebozoan Dictyostelium, we have been isolating and sequencing cDNAs that encode novel calmodulin binding proteins. The cellular and developmental functions of these genes are then studied by generation of mutants expressing various forms of the protein. We also discovered the link between calmodulin and Alzheimer’s disease and shown that many of the proteins involved in the formation of plaques and tangles are calmodulin binding proteins.

Professor O'Day is the co-inventor of DNA games including Codon, The DNA Dice Game© and Gene Rummy, The DNA Card Game©, and the inventor of Messenger, The DNA Dice Game© that are published by Carolina Biological Supply Company. Also, see videos by him at “DantonCanada” on YouTube.
