Technical Data
BLIMP1 (PR Domain Zinc Finger Protein 1, BLIMP-1, Beta-interferon Gene Positive Regulatory Domain I-binding Factor, PR Domain-containing Protein 1, Positive Regulatory Domain I-binding Factor 1, PRDI-BF1, PRDI-binding Factor 1, PRDM1)
PRDM1, an 88KDa novel transcription repressor protein is a human homolog of mouse Blimp1. It belongs to the family of PRDM protein family and contains a PR domain and 5 Kruppel Like-zinc finger motifs at the C-terminal region. It plays a pivotal role in inducing and regulating terminal differentiation of B-lymphocytes. It recruits HDAC and complex of Groucho/TLE family proteins to the DNA and actively represses vital genes required for B-cell proliferation including c-myc, CIITA promoter III, CD23b and PAX-5 promoter. PRDM1 silences IFN-gene expression by binding specifically to PRDI of the IFN gene promoter. It is continuously expressed in all Plasma cells, but is not detected in early bone marrow B-cells, memory B-cells in spleen and most germinal center B-cells. In myeloma cells, PRDI-BF1, a truncated isoform of PRDM1 is expressed that has an impaired ability to repress transcription suggesting a clinical implication.
