Abstract

Environmental glucose is an important regulator of biological processes, as it can launch different cell processes depending on its concentration. Thus, low glucose concentration can induce entry into quiescence, which ensures long-term viability for the cells or in other cases mycelial growth in the dimorphic species, which, in turn, provides the cells with fresh nutrients. Several genes, such as the genes of cAMP cascade, are involved in glucose sensing and response. Since this signal transduction pathway seemed to be an evolutionarily conserved process, we assumed that its genes were also conserved and preserved their functional homology. To obtain evidence, Schizosaccharomyces pombe rsv1 and its orthologous genes were investigated using in silico and experimental approaches. Our results supported that the Rsv1 zinc-finger transcription factors of Schizosaccharomyces japonicus and Schizosaccharomyces octosporus and the Candida albicans cas5p were really functional homologues of the S. pombe Rsv1. Namely, the homologous proteins were able to restore mutant phenotype of the S. pombe rsv1-deleted cells. Bioinformatic anaysis revealed that the most conserved parts of the proteins always contained the C2H2 domains and the complementation abilities of the counterpart genes were not uniform regarding the investigated features, which can be in connection with the conserved regions outside C2H2.
