Abstract: | "The Saccharomyces cerevisiae MID1 gene encodes a stretch-activated Ca(2+)-permeable channel. In a protein database, we found a Schizosaccharomyces pombe gene whose predicted protein shows 26% identical and 62% similar to the Mid1 channel in amino acid sequence. cDNA derived from this gene, designated yam8(+), was isolated by reverse transcription-polymerase chain reaction (RT-PCR). Further analysis showed that the Yam8 protein consists of 486 amino acids and has 6 hydrophobic segments. The yam8(+) cDNA, placed under the S. cerevisiae TDH3 promoter, partially complemented the mating pheromone-induced death (mid) phenotype of the S. cerevisiae mid1 mutant. The expression of the yam8(+) cDNA in the mid1 mutant cells partially remediated the mid phenotype and resulted in a slight increase in Ca(2+) uptake activity. These findings suggest that Yam8 is a potential homologue of Mid1" |
