Protein Structure

UniProt Annotation

Function

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.

Subcellular Localization

Nucleus.

Disease Associations

Tissue Specificity

Highly expressed in heart, skeletal muscle and placenta. Also expressed in erythroid cells.
