Identification and characterization of a novel trans-membrane protein gene, pdh1, from Schizosaccharomyces pombe

We have cloned a new gene, pdh1, from genomic DNA of fission yeast Schizosaccharomyces pombe. pdh1 is actively transcribed as 1400-nucleotide mRNA in vegetatively growing cells and can code for a 226 amino acid polypeptide (pdh1p). Computational structural prediction has revealed that the pdh1p is a highly hydrophobic protein with seven transmembrane domains. The prediction has also detected a possible C-kinase phosphorylation site within the longest hydrophilic loop.
