Xbp-1 (S) binds the sequence CCACG in ER Stress Responsive Elements (ERSE, consensus sequence CCAAT (N)9 CCACG) located upstream from many genes. The ubiquitous transcription factor NF-Y, a heterotrimer, binds the CCAAT portion of the ERSE and together the IRE1-alpha: NF-Y complex activates transcription of a set of chaperone genes including DNAJB9, EDEM, RAMP4, p58IPK, and others. This results in an increase in protein folding activity in the ER.

The EXTL1 gene is transcribed to yield mRNA and the mRNA is translated to yield exostosin-like 1 (EXTL1) protein (Wise et al. 1997, Saito et al. 1998).
The EXTL2 gene is transcribed to yield mRNA and the mRNA is translated to yield exostosin-like 2 (EXTL2) protein (Wuyts et al. 1997, Saito et al. 1998).
