Alpha-Factor secretion signal V1, optimized for Saccharomyces cerevisiae
Description
The α-mating factor is a peptide hormone produced by the yeast Saccharomyces cerevisiae, which is crucial for the mating process of these yeast cells. Here are the key details about the α-mating factor:
- Function: It is involved in the mating process of S. cerevisiae by being secreted by α-type yeast cells to attract a-type cells, facilitating the mating interaction.
- Production: Synthesized as a pre-protein that includes a signal peptide and the mature α-mating factor peptide.
- Structure and Processing:
- Pre-Pro-α-Mating Factor: Initially synthesized with a signal peptide (pre-region) that directs the nascent protein to the secretory pathway.
- Mature Peptide: After cleavage of the signal peptide, the remaining peptide is processed into the active α-mating factor.
- Processing: Includes cleavage of the signal peptide and pro-region to yield the mature peptide.
- Secretion:
- Signal Peptide Function: Directs the protein to the endoplasmic reticulum (ER), where it is cleaved for passage through the secretory pathway.
- Mature Peptide Secretion: Transported through the Golgi apparatus and secreted into the extracellular environment.
- Applications in Biotechnology:
- Protein Secretion: The α-mating factor's signal peptide is used to enhance the secretion of various proteins in yeast by attaching it to a protein of interest.
- Engineering Yeast Strains: Yeast strains can be engineered for efficient production of heterologous proteins by incorporating the α-mating factor signal peptide into their expression constructs.

Construction
The Alpha-Factor gene was synthesised and its nucleotide sequence optimised for DNA synthesis and expression in Saccharomyces cerevisiae. The gene exists in 2 versions: which limits homologous recombination in the Saccharomyces cerevisiae genome. The second version can be found here : BBa_K5143010 These two versions of the alpha-factor can be found in the following composite part:
