|HNF‑4 gamma /NR2A2 in Rat Small Intestine. HNF‑4 gamma /NR2A2 was detected in perfusion fixed paraffin-embedded sections of rat small intestine using HNF‑4 gamma /NR2A2 Monoclonal Antibody (Catalog # PP‑N3224‑00) overnight at 4 °C. Tissue was stained (brown) and counterstained with hematoxylin (blue). View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.|
Hepatocyte Nuclear Factor 4 alpha (HNF4 alpha; NR2A1) is a member of the orphan nuclear receptor family. HNF4 alpha is expressed in the liver, kidney, intestine and pancreas. Mutation of HNF4 alpha in humans has been associated with maturity-onset diabetes of the young type 1 (MODY1). HNF4 binds to DNA as an exclusive homodimer. The HNF4 alpha gene is alternatively spliced and may generate up to nine different isoforms, HNF4 alpha 1 through HNF4 alpha 9. The expression of HNF-4 gamma (NR2A2) is observed in the pancreas, kidney, small intestine, and testes with no expression detected in the liver. The level of HNF-4 gamma is less 10% than that of HNF-4 alpha.
