Research Information

During Drosophila embryogenesis, the establishment of epithelial polarity and the formation of cell-cell junctions are closely linked. I am interested in understanding the interdependence of polarity proteins and junctional proteins during embryo formation. In particular, I aim to understand the role of the adherens junction-associated protein Canoe during embryogenesis, with a focus on its interactions with Rap1 GTPase.






Bonello, T.T., Perez-Vale, K.Z., Sumigray, K.D., and Peifer, M.  (2018)  Rap1 acts via multiple mechanisms to position Canoe/Afadin and adherens junctions and mediate apical-basal polarity establishment. .
