Evaluation of synthetic peptides for direct protein delivery into Saccharomyces cerevisiae.
Efficient intracellular delivery of functional proteins into the yeast Saccharomyces cerevisiae remains a major technical challenge due to its rigid cell wall. Here, we report that synthetic peptide tags, particularly penetratin, enable nearly complete delivery of GFP, albeit with substantial cytotoxicity. This method provides a promising non-genetic platform for the intracellular delivery and functional analysis of proteins in yeast systems.
