Protein

Transcription factor MafK

Gene

Mafk

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

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.
