- Abstract: A mammalian nonclassical secretion sequence derived from mouse Engrailed2 homeoprotein (En2) was used to direct the secretion of the enhanced green fluorescent protein from Pichia pastoris. This signal peptide conferred the transport of enhanced green fluorescent protein into periplasm through an endoplasmic reticulum-golgi independent pathway, without inducing severe unfolded protein response as compared with Saccharomyces cerevisae α-factor preprosequence. This study implies that this mammalian nonclassical signal peptide could be developed as a useful tool for delivering cargoes to the cell surface of yeast.
