Structure of the compact lumenal domain of yeast Ire1Structure of the compact lumenal domain of yeast Ire1

Structural highlights

2be1 is a 3 chain structure with sequence from Saccharomyces cerevisiae. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.983Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

IRE1_YEAST Senses unfolded proteins in the lumen of the endoplasmic reticulum via its N-terminal domain which leads to enzyme auto-activation. The active endoribonuclease domain splices HAC1 precursor mRNA to produce the mature form which then induces transcription of UPR target genes.[1] [2] [3]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
