Rabbit Anti-Human HNF4A monoclonal antibody for WB, ICC/IF, IHC, FC. HNF-4 alpha is a transcription factor that binds DNA as a homodimer. HNF-4 alpha is important in liver, kidney, and intestinal development. It has also been intensely studied as one of a variety of genes responsible for diabetes mellitus. HNF-4 alpha has been shown in knock out mice to be essential for the morphogenic and functional differentiation of hepatocytes. HNF-4 alpha is a dominant regulator of epithelial phenotypes able to drive the mesenchymal-to-epithelial transition when expressed in fibroblasts.
