Pancreatic duodenal homeobox 1 (PDX1) also known as insulin promoter factor 1 (IPF1) is an important transcription factor with a molecular weight of approximately 31 kDa. PDX1 plays an essential role in the development and function of the pancreas. This protein is mainly expressed in the pancreatic beta cells where it regulates gene expression linked to insulin production. Its expression also extends to the duodenum where it influences other developmental processes.
Biological function summary

PDX1 plays a critical role in pancreatic development beta-cell differentiation and insulin gene transcription. It functions as part of a protein complex that controls key aspects of beta-cell identity and function. The interactions within this complex allow PDX1 to effectively modulate pancreatic gene expression and maintain glucose homeostasis.

Pathways

PDX1 is deeply involved in the insulin secretion pathway and the regulation of glucose metabolism. It interacts with other transcription factors such as MAFA and NEUROD1 to carry out its role in these pathways. The presence of PDX1 in these pathways ensures the proper regulation of genes essential for insulin production and release connecting it to various metabolic processes.

PDX1 associates mainly with diabetes mellitus and pancreatic agenesis. Mutations or functional impairments in PDX1 affect insulin production leading to diabetes. Furthermore in pancreatic agenesis where the pancreas fails to develop PDX1 malfunctions are often implicated. PDX1 interactions with proteins like MAFA and NEUROD1 during this process are critical; alterations in these relationships can exacerbate disease states linking PDX1 to both genetic and acquired forms of pancreatic dysfunction.

General info

Function

Activates insulin, somatostatin, glucokinase, islet amyloid polypeptide and glucose transporter type 2 gene transcription. Particularly involved in glucose-dependent regulation of insulin gene transcription. As part of a PDX1 : PBX1b : MEIS2b complex in pancreatic acinar cells is involved in the transcriptional activation of the ELA1 enhancer; the complex binds to the enhancer B element and cooperates with the transcription factor 1 complex (PTF1) bound to the enhancer A element. Binds preferentially the DNA motif 5'-[CT]TAAT[TG]-3'. During development, specifies the early pancreatic epithelium, permitting its proliferation, branching and subsequent differentiation. At adult stage, required for maintaining the hormone-producing phenotype of the beta-cell.

Sequence similarities

Belongs to the Antp homeobox family. IPF1/XlHbox-8 subfamily.

Post-translational modifications

Phosphorylated by the SAPK2 pathway at high intracellular glucose concentration. Phosphorylated by HIPK2 on Ser-268 upon glucose accumulation. This phosphorylation mediates subnuclear localization shifting. Phosphorylation by PASK may lead to translocation into the cytosol (By similarity).
