In addition, functional evidence supports a role of TmeA in intracellular development. We leveraged the lipophilic tracer DiI to reveal TmeA-dependent trafficking of plasma membrane-derived material to the chlamydial inclusion. The pathway was distinct from that described for sphingomyelin delivery to inclusions. Trafficking of DiI to the inclusion instead required actin polymerization and the TmeA Neural Wiskott-Aldrich syndrome protein (N-WASP) interaction domain. Ectopically expressed TmeA co-localized with internalized DiI in vesicle-like structures that also depended on the N-WASP binding domain. Clathrin and dynamin were also required but likely contribute independently of direct TmeA-mediated activation. Overall, our data provide evidence that\n                      <jats:italic toggle=\"yes\">Chlamydia<\/jats:italic>\n                      repurposes TmeA to accomplish development-specific tasks and parasitizes the host surface to support intracellular growth.\n                    <\/jats:p>\n                    <jats:sec>\n                      <jats:title>IMPORTANCE<\/jats:title>\n                      <jats:p>\n                        <jats:italic toggle=\"yes\">Chlamydia trachomatis<\/jats:italic>\n                        is a human pathogen and a prevalent agent of sexually transmitted diseases.
