| 別名 | Glutamine-rich protein 1, QRICH1, Transcriptional regulator QRICH1 |
| 背景 | Transcriptional regulator QRICH1 is a ~86 kDa protein. Transcriptional regulator that acts as a mediator of the integrated stress response (ISR) through transcriptional control of protein homeostasis under conditions of ER stress. Controls the outcome of the unfolded protein response (UPR) which is an ER-stress response pathway. ER stress induces QRICH1 translation by a ribosome translation re-initiation mechanism in response to EIF2S1/eIF-2-alpha phosphorylation, and stress-induced QRICH1 regulates a transcriptional program associated with protein translation, protein secretion-mediated proteotoxicity and cell death during the terminal UPR. May cooperate with ATF4 transcription factor signaling to regulate ER homeostasis which is critical for cell viability. Up-regulates CASP3/caspase-3 activity in epithelial cells under ER stress. 1.
