XBP1 is a transcription factor involved in hepatocyte growth, differentiation of plasma cells, immunoglobulin secretion, and the unfolded protein response (UPR). XBP1 regulates MHC class II genes by binding to a promoter element referred to as an X box. XBP1 also plays a role in activating unfolded protein response (UPR) target genes via direct binding to the UPR element (UPRE) during endoplasmic reticulum stress. There is an XBP1 pseudogene on chromosome 5.

XBP1 is also an estrogen-regulated gene and strongly correlates with estrogen receptor alpha (ERÎ±) expression in breast cancers.
XBP1 was one of numerous potential early detection biomarkers specific to triple-negative breast cancer in multiple pathways identified.
- Plasma biomarker profiles differ depending on breast cancer subtype but RANTES is consistently increased.
- The human PMS2L proteins do not interact with hMLH1, a major DNA mismatch repair protein.
