|Detection of Human HNF‑6/ONECUT1 by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line. PVDF Membrane was probed with 1 µg/mL of Human HNF‑6/ONECUT1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6277) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for HNF‑6/ONECUT1 at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.|
|HNF‑6/ONECUT1 in HepG2 Human Cell Line. HNF‑6/ONECUT1 was detected in immersion fixed HepG2 human hepatocellular carcinoma cell line using Human HNF‑6/ONECUT1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6277) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red, upper panel; Catalog # NL010) and counterstained with DAPI (blue, lower panel). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.|
HNF-6 (also ONECUT1; one "cut" domain family member 1; OC-1) is a monomeric 53-56 kDa member of the One Cut-domain containing class of homeodomain proteins. It is expressed in embryonic hepatic and pancreatic islet anlage, plus adult hepatocytes and intestinal epithelial cells. HNF-6 is a transcriptional activator that is known to interact with Foxa2. Genes regulated by HNF-6 include Glut2, alpha 1AT, alpha -fetoprotein and HNF-3 beta. Human HNF-6 is 465 amino acids (aa) in length. It contains two DNA-binding regions, one classified as a CUT domain (aa 283-369) and another as a homeobox domain (aa 385-444). HNF-6 is both acetylated and phosphorylated, contributing to protein stability and transactivation activity. Over aa 139-283, human HNF 6 shares 99% aa identity with mouse HNF-6. Rat HNF-6 shows a 26 aa insertion after Ala368. Given an overall aa identity of 99% between rat and human, the possibility exists that this insertion may also exist in human.
