Previous studies performed on Chlamydia trachomatis have demonstrated how these obligate intracellular microbes invade host cells through the utilization of secreted effector proteins. One secreted effector called Tarp (translocated actin recruiting protein) is implicated in cytoskeleton rearrangements that promote bacterial entry into the host cell. The focus of our study is to create a plasmid that carries the tarP gene that when transcribed and translated from within Chlamydia trachomatis will generate a c-Myc epitope tagged Tarp. The tag will be used in future studies to track the progression of the protein through the infectious process and will allow us to distinguish this protein from the Tarp effector expressed from the endogenous wild type gene. The epitope-tagged Tarp expression plasmid will be used as a template to construct Tarp deletion mutants. The mutant forms will be created in regions that have been biochemically characterized and predicted to be important to the invasion process of the pathogen. Observations on the potential phenotypes of these mutants and the possibility of allelic exchange will also be pursued in the future.
