Functioni

Since they lack a putative transactivation domain, the small Mafs behave as transcriptional repressors when they dimerize among themselves. However, they seem to serve as transcriptional activators by dimerizing with other (usually larger) basic-zipper proteins and recruiting them to specific DNA-binding sites. Small Maf proteins heterodimerize with Fos and may act as competitive repressors of the NF-E2 transcription factor. Transcription factor, component of erythroid-specific transcription factor NF-E2. Activates globin gene expression when associated with NF-E2. May be involved in signal transduction of extracellular H+ (By similarity).By similarity

Disruption phenotypei

Mice, although viable and fertile, exhibit abnormal megakaryocyte proliferation as well as age-dependent behavioral defects. Megakaryocytes display both anti-glycoprotein IIb immunoreactivity and anti-acetylcholinesterase activity.1 Publication

Expressioni

Developmental stagei

Expressed throughout the embryo up until E8.5 with strong expression in the neural tube. Expression continues throughout the embryo with some intense expression also in the epithelium of the intestine, skeletal muscle, lens, retina, cranial nerve, and dorsal root ganglion cells. After birth, strong expression in the epidermis, hair follicles, epithelium of the digestive and respiratory tracts, and kidney tubules.1 Publication

Interactioni

Subunit structurei

Homodimer or heterodimer. Homodimerization leads to transcriptional repression. Forms high affinity heterodimers with members of the CNC-bZIP family such as NFE2, NFE2L1/NRF1, NFE2L2/NRF2 and NFE2L3/NRF3. Interacts with NFE2; the interaction results in transactivation activation. Interacts with CREBBP; the interaction leads to acetylation of the basic region of MAFG and stimulation of NFE2 transcriptional activity through increased DNA binding (By similarity).By similarity
