Ire1 serine/threonine-protein kinase/endoribonuclease complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
Endoplasmic reticulum localized, type-I transmembrane homodimer which forms in response to the accumulation of unfolded protein in the ER and evokes the unfolded protein response (UPR) by splicing the mRNA encoding master transcriptional regulator of the UPR, HAC1 (P41546). IRE1 cleaves a single phosphodiester bond in each of two RNA hairpins (with non-specific base paired stems and loops of consensus sequence CNCNNGN, where N is any base) to remove an intervening intron from the target transcript. IRE1 auto-activates via transphosphorylation following binding of unfolded proteins to its N-termini.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
