Strain development Developed by Takao Iwawaki and Masayuki Miura, RIKEN Brain Science Institute. The 3.6-kb fragment of pCAX-F-XBP1deltaDBD-venus was injected into the pronuclei of C57BL/6 fertilized eggs. Transgenic mice were backcrossed to C57BL/6JJcl.  
Strain description 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. Endoplasmic reticulum (ER) stress is caused by the accumulation of unfolded proteins in the ER lumen, and is associated with vascular and neurodegenerative diseases. 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.  
Colony maintenance Carrier x Noncarrier [C57BL/6JJcl]. Tg mice are viable and fertile.
