Human Cytomegalovirus Us17 Locus Fine-Tunes Innate And Intrinsic Immune Responses, Stephen James Gurczynski

Wayne State University Dissertations

HCMV employs numerous strategies to combat, subvert, or co-opt host immunity. One evolutionary strategy for this involves "capture" of a host gene and then its successive duplication and divergence, forming a gene family, many of which have immunomodulatory activities. The HCMV US12 family consists of ten tandemly arranged sequence-related genes in the unique short region of the HCMV genome (US12-US21). Each gene encodes a protein possessing seven predicted transmembrane domains, and patches of sequence similarity with cellular GPCRs and the bax inhibitor-1 family of anti-apoptotic proteins. We show that one member, US17, plays an important role during virion maturation. Microarray …
