Transendothelial migration (TEM) of leukocytes across the endothelium is critical for inflammation. In the endothelium, TEM requires the coordination of membrane movements and cytoskeletal interactions, including, prominently, recruitment of the lateral border recycling compartment (LBRC). The scaffold protein IQGAP1 was recently identified in a screen for LBRC-interacting proteins. Knockdown of endothelial IQGAP1 disrupted the directed movement of the LBRC and substantially reduced leukocyte TEM. Expression of truncated IQGAP1 constructs demonstrated that the calponin homology domain is required for IQGAP1 localization to endothelial borders and that the IQ domain, on the same IQGAP1 polypeptide, is required for its function in TEM. …

Lawrence University Honors Projects
Biomphalaria glabrata is the intermediate host to the disease causing parasitic worm, Schistosoma mansoni. Previous work has identified homologs of NF-κB, a known immune related transcription factor, in B. glabrata and work has also been done to establish putative κB sites. It has also been observed that the p65 homologous subunit has an extended N-terminal region not present in other homologs. The goal of the present study is twofold: investigate DNA binding affinity of two NF-κB subunits, Bg-p65 and Bg-p50, and characterize the nature of the N-terminal extension of Bg-p65. In the current work, it is shown through the …
