Human PDX1 mRNA encodes the human pancreatic and duodenal homeobox 1 (PDX1) protein, a transcriptional activator of several genes, including insulin, somatostatin, glucokinase, islet amyloid polypeptide, and glucose transporter type 2. PDX1 may be involved in the early development of the pancreas. It also plays a major role in glucose-dependent regulation of insulin gene expression.
