Kinase
Pharmacology

Principal Investigator, Flora Rutaganira focused on the synthesis and optimization of potent and selective kinase inhibitors used in the context of infectious disease and asthma. As a postdoctoral researcher, she used this training to assess kinase pharmacology in choanoflagellates and establish choanoflagellates as a chemical biology model for the evolution of animal cell singling.

Chemical
Proteomics

In order to identify targets of compounds identified as hits in  phenotypic screens, we use chemical probes. We primarily have focused on kinase-directed activity based probes to identify the choanoflagellate targets of kinase inhibitors used in animals.

Chemical Genetics /
High-Content Imaging

We conduct high-throughput screening of chemical libraries with Salpingoeca rosetta, a choanoflagellate that differentiates into a rosette colony during its dynamic life history. We use high content imaging to assess S. rosetta phenotypes after treatment with structurally diverse compounds that have overlapping pharmacology based on characterized animal targets. We are excited to use this approach in combination with recently developed CRISPR-based methods to edit choanoflagellate genomes.

Stay tuned for upcoming publications!
