PDX1 Antibody / Pancreatic and duodenal homeobox 1

PDX1 antibody detects Pancreatic and duodenal homeobox 1, a transcription factor that regulates pancreatic development, beta-cell differentiation, and insulin gene expression. The UniProt recommended name is Pancreatic and duodenal homeobox 1 (PDX1). This nuclear protein functions as a master regulator of pancreatic organogenesis and endocrine function, orchestrating the transcriptional networks that specify pancreatic progenitor cells and maintain mature beta-cell identity.

Functionally, PDX1 antibody identifies a 283-amino-acid homeodomain-containing protein that binds to promoter regions of multiple pancreatic genes, including insulin, somatostatin, glucokinase, and GLUT2. PDX1 interacts with transcriptional cofactors such as PBX1, NEUROD1, and MAFA to activate insulin transcription and coordinate glucose-stimulated insulin secretion. During embryogenesis, PDX1 marks multipotent progenitors in the foregut endoderm that give rise to all pancreatic cell lineages.

The PDX1 gene is located on chromosome 13q12.2 and is highly expressed in the pancreas, particularly in beta cells of the islets of Langerhans and in the duodenal epithelium. PDX1 expression is regulated by glucose, nutrient status, and signaling pathways including PI3K/AKT and MAPK. Its activity ensures proper glucose homeostasis and metabolic regulation.

Pathologically, mutations in PDX1 cause pancreatic agenesis, maturity-onset diabetes of the young type 4 (MODY4), and contribute to type 2 diabetes through impaired beta-cell function. Loss of PDX1 expression leads to beta-cell dedifferentiation, while overexpression can promote transdifferentiation of non-beta pancreatic cells into insulin-producing phenotypes. Research using PDX1 antibody supports studies in diabetes, pancreatic development, and regenerative medicine.

PDX1 antibody is validated for western blotting, immunofluorescence, and immunohistochemistry to detect transcription factors involved in endocrine development. NSJ Bioreagents provides PDX1 antibody reagents optimized for studies in pancreatic biology, transcriptional regulation, and diabetes research.

Structurally, Pancreatic and duodenal homeobox 1 contains a highly conserved homeobox domain responsible for DNA binding and nuclear localization signals that target it to the nucleus. Post-translational modifications such as phosphorylation modulate PDX1 stability and transcriptional activity. This antibody enables investigation of PDX1's role in pancreatic morphogenesis, beta-cell identity maintenance, and metabolic gene regulation.
