MAFB (Transcription factor MafB) is a protein that switches other genes on and off. In the public catalogues the evidence so far is association rather than a proven role. Tied to Colorectal cancer. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Acts as a transcriptional activator or repressor. Plays a pivotal role in regulating lineage-specific haematopoiesis by repressing ETS1-mediated transcription of erythroid-specific genes in myeloid cells. Required for monocytic, macrophage, osteoclast, podocyte and islet beta cell differentiation. Involved in renal tubule survival and F4/80 maturation. Activates the insulin and glucagon promoters. Together with PAX6, transactivates weakly the glucagon gene promoter through the G1 element. Location: Nucleus (UniProt). Locus 20q12 (HGNC).
