Summary: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and protein dimerization activity. Involved in hindbrain development. Acts upstream of or within several processes, including embryonic organ development; hindbrain development; and liver development. Predicted to be active in nucleus. Is expressed in several structures, including digestive system; heart; neural plate; posterior neural keel; and pronephros. Human ortholog(s) of this gene implicated in kidney disease; maturity-onset diabetes of the young type 5; pancreas disease; renal cell carcinoma; and type 2 diabetes mellitus. Orthologous to human HNF1B (HNF1 homeobox B). [provided by Alliance of Genome Resources, Dec 2024]

Knockdown of pk1a led to decreased expression of vhnf1, a homeodomain gene previously shown to be involved in biliary development and in kidney cyst formation; forced expression of vhnf1 mRNA led to rescue of the pk1a morphant phenotype

It was concluded that hnf1b(hi2169) is hypomorphic to hnf1b(hi1843) and that, while hnf1b is required for r5/r6 gene expression in the hindbrain, r5/r6 gene expression can be experimentally induced independently of hnf1b anterior to the hindbrain.

vHNF1 plays crucial role at the earliest steps of liver induction: the acquisition of endoderm competence and the hepatic specification.

Data show that zebrafish mutants for Tcf2 fail to specify a single lumen in their gut tube and instead develop multiple lumens, and show that Tcf2 controls single lumen formation by regulating claudin15 and Na+/K+-ATPase expression.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
