Dr. Hill’s research deals with the genetic determinants of growth and division in fungal cells.  Particular areas of interest are the identification of proteins participating in construction and constriction of actomyosin rings at division sites and the molecular basis for targeting of proteins to their sites of action in the cell. In collaboration with Dr. Loretta Jackson-Hayes (Department of Chemistry), this laboratory is generating and characterizing mutant strains of the filamentous fungus Aspergillus nidulans that have defects in cell growth or division, which is providing information on the mechanisms underlying these processes.  Among genes currently under study, are actin, type II myosin, protein kinase C, and a fungal IQGAP protein.   Other recently published work has dealt with proteins in the fungal Golgi apparatus, which are important to protein glycosylation and to cell morphogenesis.  The cells pictured at the left are those of fungi bearing a mutation in the Golgi membrane transporter for GDP-mannose.  Their distorted shapes relate to failure to correctly glycosylate glycoproteins involved in structure of cell walls.
