      Background InformationTranscription factor PDX1, also known as pancreatic and duodenal homeobox 1, activates expression of the insulin and somatostatin genes. This protein is a key regulator of islet peptide hormone expression and also plays an essential role in pancreatic development. It has been shown to interact with the basic helix-loop-helix domains of TCF3(E47) and NEUROD1 and with HMG-I(Y). This protein also interacts with the methyltransferase SETD7. Mutations in this gene may be involved in several disorders of the pancreas or in diabetes mellitus.
      Product Information

      UniProt Number
      UniProt SummaryFUNCTION: Activates insulin and somatostatin gene transcription. Key regulator of islet peptide hormone expression but also responsible for the development of the pancreas, most probably by determining maturation and differentiation of common pancreatic precursor cells in the developing gut. Binds the DNA sequence 5'-CC[CT]TAATGGG-3'.

      SUBUNIT STRUCTURE: Interacts with the basic helix-loop-helix domains of TCF3(E47) and NEUROD1 and with HMG-I(Y). Interacts with the methyltransferase SETD7 By similarity. Interacts with SPOP.


      TISSUE SPECIFICITY: Duodenum and pancreas (Langerhans islet beta cells and small subsets of endocrine non-beta-cells, at low levels in acinar cells).

      DEVELOPMENTAL STAGE: At 8.5 dpc, detected in the gut epithelium from which the pancreatic buds are formed. Transient expression in pancreatic ducts, endocrine and acinar cells. Down-regulated around 10.5 dpc when expression becomes restricted to differentiated beta-cells.

      DOMAIN: The Antp-type hexapeptide mediates heterodimerization with PBX on a regulatory element of the somatostatin promoter (By Similarity).

      The homeodomain, which contains the nuclear localization signal, not only mediates DNA-binding, but also acts as a protein-protein interaction domain for TCF3(E47), NEUROD1 and HMG-I(Y) (By Similarity).

      PTM: Phosphorylated by the SAPK2 pathway at high intracellular glucose concentration.

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

      Contains 1 homeobox DNA-binding domain.
