Gene Information

human ... MAFA(389692)

General description

MAFA is a transcription factor that binds RIPE3b, a conserved enhancer element that regulates pancreatic beta cell-specific expression of the insulin gene (INS; MIM 176730) (Olbrot et al., 2002 [PubMed 12011435]).[supplied by OMIM

Immunogen

MAFA (NP_963883, 222 a.a. ~ 308 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Biochem/physiol Actions

MAF bZIP transcription factor A (MAFA) modulates genes which are involved in pancreatic β-cell function and the protein itself is critical for the functioning of β-cells. It functions as a regulator to enhance the expression of genes which have a role in glucose-induced insulin secretion.

Physical form

Solution in phosphate buffered saline, pH 7.4

Phosphorylation regulates transcription factor activity by influencing dimerization, cellular localization, activation potential, and/or DNA binding. Nevertheless, precisely how this post-translation modification mediates these processes is poorly understood. Here, we examined the role of phosphorylation on the DNA-binding properties of MafA

The beta cell transcriptional factor musculoaponeurotic fibrosarcoma oncogene family A (MafA) regulates genes important for beta cell function. Loss of nuclear MafA has been implicated in beta cell dysfunction in animal models of type 2 diabetes. We sought to establish

MafA, a basic-leucine zipper transcription factor that is important to pancreatic β-cell function, is regulated by several intricate mechanisms. MafA undergoes extensive posttranslational modification by phosphorylation, ubiquitination and sumoylation, and these modifications regulate the turnover, DNA binding and transactivation function
