The protein MAFF also known as v-maf avian musculoaponeurotic fibrosarcoma oncogene homolog F functions as a transcription factor. It is a small protein with a molecular mass of approximately 18 kDa. MAFF is expressed in various tissues including the brain liver and pancreas. It belongs to the small Maf family characterized by their lack of transcriptional activation domains necessitating dimerization with other proteins to regulate gene expression.
Biological function summary

The small Maf protein MAFF plays an important role in regulating oxidative stress response and the coordinated expression of genes involved in detoxification processes. When part of a complex it often dimerizes with Nrf2 a protein that activates the expression of antioxidant response elements (ARE) in gene promoters. This kind of dimerization enables MAFF to indirectly regulate the transcription of genes involved in the cellular protection against oxidative damage.

Pathways

MAFF integrates into the antioxidant defense mechanism especially through its interaction with the Nrf2-Keap1 signaling pathway. Within this pathway MAFF through its interaction with Nrf2 facilitates the induction of cytoprotective genes that help in detoxification and maintaining cellular redox homeostasis. The interaction between MAFF and Nrf2 is significant as Nrf2 becomes stabilized and translocates to the nucleus under oxidative stress which is key for the pathway's protective effects.

MAFF through its interaction mainly with Nrf2 is associated with conditions like cancer and neurodegenerative diseases. In cancer the deregulation of the Nrf2 pathway often involving MAFF can lead to resistance against chemotherapy due to enhanced cellular antioxidant defenses therefore promoting tumor survival. Additionally in neurodegenerative disorders the inefficient activation of the MAFF-Nrf2 pathway may contribute to the accumulation of oxidative damage an underlying factor in diseases like Alzheimer's.

General info

Function

Since they lack a putative transactivation domain, the small Mafs behave as transcriptional repressors when they dimerize among themselves (PubMed : 8932385). However, they seem to serve as transcriptional activators by dimerizing with other (usually larger) basic-zipper proteins, such as NFE2L1/NRF1, and recruiting them to specific DNA-binding sites. Interacts with the upstream promoter region of the oxytocin receptor gene (PubMed : 16549056, PubMed : 8932385). May be a transcriptional enhancer in the up-regulation of the oxytocin receptor gene at parturition (PubMed : 10527846).
