Previous GeneCards Identifiers for MAFF Gene
The protein encoded by this gene is a basic leucine zipper (bZIP) transcription factor that lacks a transactivation domain. It is known to bind the US-2 DNA element in the promoter of the oxytocin receptor (OTR) gene and most likely heterodimerizes with other leucine zipper-containing proteins to enhance expression of the OTR gene during term pregnancy. The encoded protein can also form homodimers, and since it lacks a transactivation domain, the homodimer may act as a repressor of transcription. This gene may also be involved in the cellular stress response. Multiple transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jun 2009]
GeneCards Summary for MAFF Gene
MAFF (MAF BZIP Transcription Factor F) is a Protein Coding gene. Diseases associated with MAFF include Fibrosarcoma and Autosomal Dominant Adult-Onset Proximal Spinal Muscular Atrophy. Among its related pathways are Tacrolimus/Cyclosporine Pathway, Pharmacodynamics and Myometrial Relaxation and Contraction Pathways. Gene Ontology (GO) annotations related to this gene include DNA-binding transcription factor activity and sequence-specific DNA binding. An important paralog of this gene is MAFK.
UniProtKB/Swiss-Prot Summary for MAFF Gene
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:8932385, PubMed:16549056). May be a transcriptional enhancer in the up-regulation of the oxytocin receptor gene at parturition (PubMed:10527846).
