PRDM1/Blimp1 (PR domain zinc finger protein 1, PR domain-containing protein 1, Beta-interferon gene positive regulatory domain I-binding factor, BLIMP-1, Positive regulatory domain I-binding factor 1, PRDI-binding factor 1, or PRDI-BF1, or Beta-lymphocyte-induced maturation protein 1) is one of several transcription factors which drives the maturation of B-lymphocytes into Ig secreting cells. In the nucleus, PRDM1/BLIMP1 functions as a transcriptional repressor that binds specifically to the PRDI element in the promoter of the beta-interferon gene. Transcription of the PRDM1 gene is increased upon virus induction. PRDM1/Blimp1 also interacts with PRMT5. Two alternatively spliced transcript variants that encode different isoforms have been reported.

This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to a region near the C-terminus of human, mouse, and rat PRDM1/BLIMP1.
