Target Background

Function
Endoplasmic reticulum (ER) membrane-resident kinase/endoribonuclease involved in unfolded protein response (UPR). Initiates the selective decay of a subset of ER-localized-mRNAs that is required to survive ER stress. Rather than relying on a transcriptional program to up-regulate genes that enhance ER protein folding capacity as in S.cerevisiae, S.pombe cells reduce the amount of specific proteins entering the organelle by decreasing the level of ER-targeted mRNAs using ire1-dependent mRNA degradation. The sole mRNA cleaved upon ire1 activation that escapes decay is the ER chaperone bip1 mRNA which is more stable and hence is present at an increased steady-state after ire1 cleavage. Promotes ER stress-induced ER-phagy and via up-regulation of the protein level of the ER-phagy receptor epr1 (Ref.5).
Gene References into Functions
  1. These results reveal that the unfolded protein response in Schizosaccharomyces pombe executes selective degradation of endoplasmic reticulum-bound mRNAs in an intricate interplay between Ire1, translation, and the mRNA no-go-decay pathway, and establish a critical role for mRNA no-go-decay in maintaining endoplasmic reticulum homeostasis.
