MAFG

Gene
Mafg
Protein
Transcription factor MafG
Organism
Rattus norvegicus
Length
189 amino acids
Function
Since they lack a putative transactivation domain, the small Mafs behave as transcriptional repressors when they dimerize among themselves (By similarity). 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 (By similarity). Small Maf proteins heterodimerize with Fos and may act as competitive repressors of the NFE2L2 transcription factor (By similarity). Transcription factor, component of erythroid-specific transcription factor NFE2L2 (By similarity). Activates globin gene expression when associated with NFE2L2 (By similarity). May be involved in signal transduction of extracellular H(+) (PubMed:11583919).
Similarity
Belongs to the bZIP family. Maf subfamily.
