Post-translational prenylation mechanisms, including farnesylation and geranylgeranylation, mediate both subcellular localization and protein-protein interaction in eukaryotes. The farnesyltransferase (FT) enzyme complex is composed of two subunits: the alpha-subunit, an essential protein shared with the geranylgeranyltransferase complex; and a beta-subunit, termed Ram1. FT activity is an important mediator of Ras pathway signaling via control of Ras protein localization. Our previous data show that A. fumigatus RasA localizes primarily to the plasma membrane where it functions in processes controlling morphogenesis and virulence. However, the importance of FT activity to Ras protein function, filamentous fungal growth, and A. fumigatus virulence is currently unknown. To explore this, we generated an A. fumigatus deletion mutant lacking the FT beta-subunit (ram1KO). Conidial germination rate was reduced in the ram1KO mutant, with a concomitant reduction in conidial viability of 45%. Although no polarity defects of hyphae were apparent, the ram1KO mutant displayed reduced radial growth rate, an average increase in hyphal width of 26%, and altered nuclear positioning in growing hyphae. Furthermore, loss of ram1 resulted in resistance to triazole antifungal drugs such as voriconazole. Complementation of the ram1KO mutant with the ram1 gene (ram1KO+ram1) restored the wild-type phenotype for each of these processes. To define molecular mechanisms for Ram1-mediated processes, we generated strains expressing GFP-RasA in the ram1KO genetic background. The absence of ram1 resulted in mislocalization of RasA from the plasma membrane. Interestingly, mutation of RasA to enhance selectivity for geranylgeranylation as an alternative membrane targeting mechanism in the absence of Ram1 restored RasA plasma membrane localization but not radial growth. These data suggest that Ras-independent mechanisms are at least partially responsible for phenotypes exhibited by the ram1KO mutant. Together, these data point to a crucial role for the Ram1 farnesyltransferase in mediating A. fumigatus growth and antifungal susceptibility.

Blueprint for the Future—Dr. David Wood, Dr. Mary Burtnick, Dr. Jonathon Audia and Dr. Paul Brett, make plans to develop a new biosafety lab with the NIH award.
The Laboratory of Infectious Diseases was designed so that research with highly infectious agents could be safely conducted. It is a free-standing, high containment laboratory, built according to NIH standards for a Biosafety Level-3 research unit. The Medical Science Building has laboratories and classrooms to accommodate both medical and graduate students. The LID opened February of 2015.
Dr. Paul Brett Awarded $1.7 million by DTRA

The award will cover a three-year study period.
According to Dr. Brett, the award will enable his lab to characterize the protective capacity of several promising vaccine candidates that they have developed for immunization against diseases caused by Burkholderia pseudomallei and Burkholderia mallei, the causative agents of melioidosis and glanders.
March 12, 2014, Dr. David Wood, professor and chair of the department of microbiology and immunology at the USA College of Medicine, will give a presentation at the 2014 International Conference of Biocontainment Facilities on April 10, 2014.

USA 2012 Distinguished Alumni Award recipient Terrence Tumpey, Ph.D.
Distinguished Alumni Award
Dr. Terrence Tumpey has established himself as a world-renowned expert on one of mankind's most devastating pathogens - the influenza virus. Under high biosafety levels, Dr. Tumpey examines the genetic requirements that determine how influenza adapts to different hosts and can be spread from one host to another.for example, from birds to humans. He traveled to Vietnam during the initial stages of the bird flu outbreak to isolate and subsequently analyze highly pathogenic influenza virus from poultry flocks.
Dr. Tumpey reconstructed the pandemic Spanish Influenza Virus that caused- the 1918 epidemic. This accomplishment provided insight into what genes made this virus so deadly, and it brought Dr. Tumpey international recognition and established his laboratory as a leader in influenza research.
His account of this research, published in Science, was honored with the Lancet Award, which recognized it as the top scientific paper of 2005. He has also received the 2006 and 2008 Shepard Award from the Centers for Disease Control and Prevention for Ou tstanding Research Papers.
Dr. Tumpey, who earned his bachelor's degree in biology from the University of Minnesota, Duluth, received his Ph.D. from the University of South Alabama in 1997, working in the laboratory of Dr. Robert Lausch in the department of microbiology and immunology. His outstanding doctoral work examining herpes infection 01 the eye and the host immune response to infection led to the awarding of an American Society for Microbiology Postdoctoral Fellowship at the Centers for Disease Control in Atlanta. He went on to nold positions at the University of Georgia and the Southeast Poultry Research Lab in Athens, Ga.
Since 2003, Dr. Tumpey has been with the CDC and is currently a microbiologist and team leader of pathogenesis, within the Immunology and Pathogenesis Branch. His research on pathogenesis . and immunity during the last 22 years is documented in 153 total peer-reviewed publications. Dr. Tumpey was appointed to the Editorial board of the Journal of Virology in 2006 and in 2007 was inducted into the University of Minnesota, Duluth Academy of Science and Engineering.
He and his wife, Abbigail, have two sons, Blake and Pierce.
