The RHO1 homologue of Cryptococcus neoformans complemented Saccharomyces cerevisiae rho1 mutations. The results of overexpression and site-specific mutagenesis of CnRHO1 in C. neoformans and S. cerevisiae indicated that although CnRHO1 could functionally substitute for the RHO1 gene of S. cerevisiae, mutants of cnrho1 manifested unique features in certain aspects.
