Endoplasmic reticulum (ER) stress is caused by the accumulation of unfolded proteins in the ER lumen, and is associated with vascular and neurodegenerative diseases. ERAI (ER stress-activated indicator) transgenic mice carry human XBP1 and venus (a variant of green fluorescent protein) fusion gene under control of a CAG promoter. The transcripts from ERAI constructs are spliced under ER stress, the spliced mRNA is translated into an XBP1-venus fusion protein, which can be detected by fluorescence of the venus. This strain is useful to monitor physiological and pathological ER stress in vivo.
