The unfolded protein response in Pichia pastoris without external stressing stimuli

Abstract excerpt

Dysfunction or capacity shortage of the endoplasmic reticulum (ER) is cumulatively called ER stress and provokes the unfolded protein response (UPR). In various yeast species, the ER-located transmembrane protein Ire1 is activated upon ER stress and performs the splicing reaction of HAC1 mRNA, the mature form of which is translated into a transcription factor protein that is responsible for the transcriptome...
