Mouse Anti-MAFA (Transcription Factor MafA, Pancreatic beta-cell-specific Transcriptional Activator, Transcription Factor RIPE3b1, V-maf Musculoaponeurotic Fibrosarcoma Oncogene Homolog A)
MafA is a 352aa containing transcription factor playing an important part in the regulation of the insulin gene transcription. It belongs to the bZIP family and Maf subfamily with a bZIP domain and binds DNA as a homodimer. Transcription factor MafA binds to RIPE3b, a conserved enhancer element that regulates pancreatic beta cell-specific expression of the insulin gene. MafA is known to cooperate synergistically with NEUROD1 and PDX1 and is known to be up-regulated by glucose. It is detected in nuclei of pancreas islet beta cells.
