Abstract: | "A putative MAP-kinase kinase-encoding gene, CaSTE7, was isolated from Candida albicans by complementation of ste7 and ste11 mutants of the pheromone signal-transduction pathway of Saccharomyces cerevisiae. The nucleotide (nt) sequence revealed an ORF of 1767 nt encoding a putative protein of 589 amino acids (aa). CaSTE7 has a strong homology with MAP-kinase kinase STE7 of S. cerevisiae, the kinase domain having 45% homology with that of STE7. The deduced aa sequence contained all eleven consensus kinase subdomains found in MAP-kinase kinases. It can suppress the mating defect of ste5, ste11, ste7, and fus3 kss1 double mutants, but it cannot bypass the ste12 mutation. CaSTE7 behaves as a hyperactive allele of STE7, suppressing the mating defects of the pheromone signal-transduction pathway by constitutively stimulating STE12, and hence STE12-dependent processes" |
