DESCRIPTION

Also known as MAFG_MOUSE, Mafg. Since they lack a putative transactivation domain, the small Mafs behave as transcriptional repressors when they dimerize among themselves (PubMed:16738329, PubMed:9679061). However, they seem to serve as transcriptional activators by dimerizing with other (usually larger) basic-zipper proteins, such as NFE2, NFE2L1 and NFE2L2, and recruiting them to specific DNA-binding sites (PubMed:16738329, PubMed:9679061). Small Maf proteins heterodimerize with Fos and may act as competitive repressors of the NFE2L2 transcription factor. Transcription factor, component of erythroid-specific transcription factor NFE2L2. Activates globin gene expression when associated with NFE2L2 (By similarity). May be involved in signal transduction of extracellular H(+) (By similarity). Homodimer or heterodimer (By similarity). Homodimerization leads to transcriptional repression (By similarity). Forms high affinity heterodimers with members of the CNC-bZIP family such as NFE2, NFE2L1/NRF1, NFE2L2/NRF2 and NFE2L3/NRF3 (PubMed:31398338). 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).
