Target

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. 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. -
Tissue specificity
Duodenum and pancreas (Langerhans islet beta cells and small subsets of endocrine non-beta-cells, at low levels in acinar cells). -
Involvement in disease
Defects in PDX1 are a cause of pancreatic agenesis (PAC) [MIM:260370]. This autosomal recessive disorder is characterized by absence or hypoplasia of pancreas, leading to early-onset insulin-dependent diabetes mellitus. This was found in a frameshift mutation that produces a truncated protein and results in a second initiation that produces a second protein that act as a dominant negative mutant.
Defects in PDX1 are a cause of non-insulin-dependent diabetes mellitus (NIDDM) [MIM:125853]; also known as diabetes mellitus type 2. NIDDM is characterized by an autosomal dominant mode of inheritance, onset during adulthood and insulin resistance.
Defects in PDX1 are the cause of maturity-onset diabetes of the young type 4 (MODY4) [MIM:606392]; also symbolized MODY-4. MODY is a form of diabetes that is characterized by an autosomal dominant mode of inheritance, onset in childhood or early adulthood (usually before 25 years of age), a primary defect in insulin secretion and frequent insulin-independence at the beginning of the disease. -
Sequence similarities
Belongs to the Antp homeobox family. IPF1/XlHbox-8 subfamily.
Contains 1 homeobox DNA-binding domain. -
Domain
The Antp-type hexapeptide mediates heterodimerization with PBX on a regulatory element of the somatostatin promoter.
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). -
Post-translational
modificationsPhosphorylated by the SAPK2 pathway at high intracellular glucose concentration. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-PDX1 antibody (ab47267)Image from Zhang Y et al., PLoS One. 2012;7(5):e36675. Epub 2012 May 7. Fig 7.; doi:10.1371/journal.pone.0036675; May 7, 2012, PLoS ONE 7(5): e36675.Immunohistochemical analysis of murine pancreatic islets, staining PDX1 (red) with ab47267.
Tissue was fixed in formalin, permeablized with 0.25% Triton X-100, and blocked in blocking solution for 1 hour at room temperature; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody overnight at 4°C and a fluorescent-conjugated anti-rabbit IgG was used as the secondary antibody. -

Tissue underwent fixation in formaldehyde, heat mediated antigen retrieval in citrate buffer pH6.0 and blocking for 15 minutes at 20°C. The primary antibody was diluted 1/500 and incubated with sample for 45 minutes at 20°C. A HRP-conjugated goat polyclonal to rabbit IgG was used undiluted as secondary.
