Application

ISRIB (integrated stress response inhibitor) has been used as an inhibitor of integrated stress response.

Biochem/physiol Actions

ISRIB (integrated stress response inhibitor) as a drug, imparts resistance to the cells against the downstream effects of eukaryotic initiation factor 2 (eIF2)α phosphorylation such as activating transcription factor 4 (ATF4) and eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1) induction.
ISRIB is a blood- brain barrier penetrant, potent and selective inhibitor of integrated stress response (ISR) that impairs adaptation to ER stress. ISRIB is a potent inhibitor of PERK signaling, which potently reverses the effects of eIF2a phosphorylation and restores the cells translation capacity. ISRIB enhances cognitive memory in rodents.

Repeat-associated non-AUG-initiated translation of expanded CGG repeats (CGG RAN) from the FMR1 5'-leader produces toxic proteins that contribute to neurodegeneration in fragile X-associated tremor/ataxia syndrome. Here we describe how unexpanded CGG repeats and their translation play conserved roles in regulating

Common fragile sites (CFSs) are genomic regions frequently involved in cancer-associated rearrangements. Most CFSs lie within large genes, and their instability involves transcription- and replication-dependent mechanisms. Here, we uncover a role for the mitochondrial stress response pathway in the regulation

Dysregulation of cellular protein synthesis is linked to a variety of diseases. Mutations in EIF2S3, encoding the γ subunit of the heterotrimeric eukaryotic translation initiation factor eIF2, cause MEHMO syndrome, an X-linked intellectual disability disorder.
