Enables DNA-binding transcription factor activity; promoter-specific chromatin binding activity; and sequence-specific DNA binding activity. Contributes to DNA-binding transcription factor activity, RNA polymerase II-specific. Involved in several processes, including animal organ development; detection of glucose; and regulation of transcription, DNA-templated. Located in nucleus. Colocalizes with cytoplasm. Biomarker of acute necrotizing pancreatitis; hyperglycemia; placental insufficiency; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in cerebral infarction; hyperglycemia; maturity-onset diabetes of the young type 4; pancreatic agenesis; and type 2 diabetes mellitus. Orthologous to human PDX1 (pancreatic and duodenal homeobox 1). [provided by Alliance of Genome Resources, Apr 2022]
