Anti-MAFA Picoband® Antibody

MAFA is a transcription factor that binds RIPE3b, a conserved enhancer element that regulates pancreatic beta cell-specific expression of the insulin gene. It is mapped to 8q24.3.

Transcription factor MafA; Pancreatic beta-cell-specific transcriptional activator; RIPE3b1 factor; V-maf musculoaponeurotic fibrosarcoma oncogene homolog A; MAFA

Transcription factor that activates insulin gene expression. Acts synergistically with NEUROD1/BETA2 and PDX1. Binds the insulin enhancer C1/RIPE3b element. Binds to consensus TRE-type MARE 5'-TGCTGACTCAGCA-3' DNA sequence.
