Abstract: | "Utilizing a screening method designed for the identification of genes involved with enhanced protein secretion in Saccharomyces cerevisiae we identified a gene, which we named PSE-1 (Protein Secretion Enhancer). Overexpression of PSE-1 in a multi-copy plasmid, as shown by Northern hybridization, gave a fourfold enhancement in total protein secretion. The repertoire of proteins that are found to be secreted in greater quantities include three known biologically active proteins: k1 killer toxin, alpha-factor, and acid phosphatase. The PSE-1 gene is located on chromosome XII of the yeast genome and codes for a hydrophobic protein containing 1089 amino acids. Haploid yeast cells that contained a LEU2 insertion mutation in PSE-1 grow very poorly, a phenotype similar to other conditional SEC mutants at restrictive temperature" |
