Research interests: I am interested in the study of cell division in D. discoideum, with a special emphasis in cytokinesis. Initially, I explored and developed different ways to trigger gene silencing in Dictyostelium as a first approach to study cytokinesis-related proteins. Further work included the targeting by RNAi of putative components of the centrosome and exocyst, including DdExo70, DdSec15, DdSun1, DdCenB, DdPLK and DdAurK. The phenotypes obtained were critical to confirm the involvement of these proteins in cell division and helped us determine which proteins we were interested in pursuing. Most of our efforts were focused on the putative centrosomal protein DdCenB, which has been shown to be required for centriolar division in human cells and SPB duplication in yeast. Interestingly, we have no evidence that DdCenB localizes at the centrosome. We are currently working to determine DdCenB cellular function. In addition, work on DdSun1, one of the proteins responsible for the anchoring of the centrosome at the nucleus, and the mitotic kinase DdPLK continue as collaborations.
