Abstract
The present invention provides RBT1 polynucleotides, including RBT1 polynucleotides encoding Rbt1, and Rbt1 polypeptides, from Candida albicans. Expression of the RBT1 gene is upregulated by the inactivation of the TUP1 gene and by environmental conditions that induce filamentous growth. Disruption of TUP1 finction in C. albicans is associated with filament fonnation as well as low infectivity. These RBT1 polynucleotide and Rbtl polypeptide sequences (and anti-Rbt1 antibodies derived from Rbt1 polypeptides) may be used in methods of detecting C. albicans sequences in a biological sample. Further, the invention provides methods for screening agents which may control C. albicans virulence and compositions comprising these agents.
