Research Backgrounds
Acts as a transcriptional activator or repressor. Plays a pivotal role in regulating lineage-specific hematopoiesis 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. SUMO modification controls its transcriptional activity and ability to specify macrophage fate. Binds element G1 on the glucagon promoter (By similarity). Involved either as an oncogene or as a tumor suppressor, depending on the cell context.
Phosphorylated by GSK3 and MAPK13 on serine and threonine residues.
Sumoylated. Sumoylation on Lys-32 and Lys-297 stimulates its transcriptional repression activity and promotes macrophage differentiation from myeloid progenitors (By similarity).
Nucleus.
Ubiquitous.
Homodimer or heterodimer with other bHLH-Zip transcription factors. Binds DNA as a homodimer or a heterodimer. Forms homodimers and heterodimers with FOS, FOSB and FOSL2, but not with JUN proteins (JUN, JUNB and JUND). Interacts with PAX6; the interaction is direct. Interacts with ETS1 and LRP1 (By similarity). Interacts with the intracellular cytoplasmic domain of LRP1 (LRPICD); the interaction results in a moderate reduction of MAFB transcriptional potential.
The leucine-zipper domain is involved in the interaction with LRPICD.
Belongs to the bZIP family. Maf subfamily.
