Involvement of the IRE1α-XBP1 Pathway and XBP1s-Dependent Transcriptional Reprogramming in Metabolic Diseases
1 Jan 2015
Abstract excerpt
The X-box binding protein 1 (XBP1) is not only an important component of the unfolded protein response (UPR), but also an important nuclear transcription factor. Upon endoplasmic reticulum stress, XBP1 is spliced by inositol-requiring enzyme 1 (IRE1), thereby generating functional spliced XBP1 (XBP1s). XBP1s functions by translocating into the nucleus to initiate transcriptional programs that regulate a subset of...
