Go Annotations as Summary Text (Tabular View) (GO Graph)

GO curators for mouse genes have assigned the following annotations to the gene product of Pdx1. (This text reflects annotations as of Thursday, July 24, 2014.)
Summary from NCBI RefSeq


[Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a transcriptional activator of several genes, including insulin, somatostatin, glucokinase, islet amyloid polypeptide, and glucose transporter type 2. The encoded nuclear protein is involved in the early development of the pancreas and plays a major role in glucose-dependent regulation of insulin gene expression. Defects in this gene are a cause of pancreatic agenesis, which can lead to early-onset insulin-dependent diabetes mellitus (NIDDM), as well as maturity onset diabetes of the young type 4 (MODY4).
