XBP1
XBP1
A gene on chromosome 22q12.1 that encodes a bZIP protein transcription factor, which regulates MHC class-II genes by binding to a promoter element or X box.Molecular pathology
XBP1 binds to a T-cell leukaemia virus type-1 promoter, and may increase expression of viral proteins by acting as the DNA binding partner of a viral transactivator.
