- Bach2 is a transcription factor, essential for B-cells.
- PRDM1 encodes Blimp-1, the master regulator of plasma cells.
- PRDM2 act as a transcriptional activator of the heme-oxygenase-1 gene.
- Transcription elongation factor ELL2 drives Ig secretory specific mRNA production (2,3)
Heme regulates B-cell differentiation, antibody class switch and hemeoxygenase-1 expression in B cells as a ligand of Bach2 (2).
Heme inhibits Bach2.
Bach2 inhibits Blimp-1.
Blimp-1 activates ELL2.
Ig classes are dysregulated in some ME patients (4).
Some ME patients have reduced representation of pathways for heme biosynthesis (5).
