== Publication Abstract from PubMed ==
Legionella pneumophila is a freshwater bacterium that replicates in predatory amoeba and alveolar macrophage. The ability of L. pneumophila to thrive in eukaryotic host cells is conferred by the Legionella containing vacuole (LCV). Formation and intracellular trafficking of the LCV is governed by an arsenal of effector proteins, many of which are secreted by the Icm/Dot Type 4 Secretion System. One such effector, known as LpnE (L. pneumophila Entry), has been implicated in facilitating bacterial entry into host cells, LCV trafficking and substrate translocation. LpnE belongs to a subfamily of tetratricopeptide repeat proteins known as Sel1-like repeats (SLRs). All eight of the predicted SLRs in LpnE are required to promote host cell invasion. Herein, we report that LpnE(1-375) localizes to cis-Golgi in HEK293 cells via its signal peptide (aa 1-22). We further verify the interaction of LpnE(73-375) and LpnE(22-375) with Oculocerebrorenal syndrome of Lowe protein (OCRL) residues 10-208, restricting the known interacting residues for both proteins. To further characterize the SLR region of LpnE, we solved the crystal structure of LpnE(73-375) to 1.75A resolution. This construct comprises all SLRs, which are arranged in a super-helical fold. The alpha-helices forming the inner concave surface of the LpnE super-helix suggest a potential protein-protein interaction interface. This article is protected by copyright. All rights reserved.
