These HNF4 ELISA kits are immunodetection tools for measuring the levels of HNF4 in biological samples. HNF4 is an alias of the human HNF4A gene, which encodes the protein, hepatocyte nuclear factor 4 alpha. Notably, HNF4 is known to play a role in cell differentiation and cholesterol metabolism and homeostasis, among other functions. The HNF4A protein is 474 amino acid residues in length and 52.8 kilodaltons in mass. However, as many as 7 protein isoforms have been identified. It is localized to the nucleus of the cell. This protein is known to be acetylated and phosphorylated. Other names for this target antigen include FRTS4 and HNF4a7.
