Intracellular Signaling From the Endoplasmic Reticulum to the Nucleus

Annu Rev Cell Dev Biol. 1998;14:459-85. doi: 10.1146/annurev.cellbio.14.1.459.


Cells respond to an accumulation of unfolded proteins in the endoplasmic reticulum (ER) by increasing transcription of genes encoding ER resident proteins. The information is transmitted from the ER lumen to the nucleus by an intracellular signaling pathway called the unfolded protein response (UPR). Recent work has shown that this signaling pathway utilizes several novel mechanisms, including translational attenuation and a regulated mRNA splicing step. In this review we aim to integrate these recent advances with current knowledge about maintenance of ER composition and abundance.
