      Description TCF Reporter Plasmid Kit
      Overview FOPflash: Transfection grade T cell factor (TCF) reporter plasmid containing two full and one incomplete copy of the TCF binding site (mutated) followed by three copies in the reverse orientation, upstream of the Thymidine Kinase (TK) minimal promoter and Luciferase open reading frame. This plasmid serves as a negative control to TOPflash which contains wild type TCF binding sites.

      TOPflash: Transfection grade T-cell factor (TCF) reporter plasmid containing two sets (with the second set in the reverse orientation) of three copies of the TCF binding site (wild type) upstream of the Thymidine Kinase (TK) minimal promoter and Luciferase open reading frame. FOPflash containing mutated TCF binding sites is also available as a negative control.

      Background Information The Wnt family encodes secreted glycoproteins implicated in cell growth regulation, cell fate determination, organogenesis and oncogenesis. Inferred from genetic analysis of wingless (wg) signaling in Drosophila, in mammalian cells, Wnts signal through the Frizzled family of receptors, to Dishevelled. Dishevelled down regulates glycogen synthase kinase-3ß (GSK-3ß) activity. This results in the stabilization and accumulation of cytosolic ß-catenin, a GSK-3ß substrate, which when phosphorylated by GSK-3ß, is targeted for ubiquitin-mediated proteolysis. ß-catenin then translocates to the nucleus, where in complexes with members of the Tcf/LEF family of transcription regulators, activates transcription of Tcf-responsive genes. This Tcf-reporter plasmid, along with FOPFLASH (Cat. # 21-169) enables quantitation of Wnt/Wg signaling in cells transfected with these constructs.

      Biological Information
      Entrez Gene Number
      Entrez Gene Summary This gene encodes transcription factor 4, a basic helix-turn-helix transcription factor. The encoded protein recognizes an Ephrussi-box ('E-box') binding site ('CANNTG') - a motif first identified in immunoglobulin enhancers. This gene is expressed predominantly in pre-B-cells, although it is found in other tissues as well. Multiple alternatively spliced transcript variants that encode different proteins have been described.
      Gene Symbol
      • TCF1
      • HNF1a
      • LFB1
      • HNF1A
      • TCF-1
      • HNF-1A
      • HNF1
      • MODY3
      UniProt Number
      UniProt Summary FUNCTION: SwissProt: P20823 # Required for the expression of several liver specific genes. Binds to the inverted palindrome 5'-GTTAATNATTAAC-3'.
      SIZE: 631 amino acids; 67356 Da
      SUBUNIT: Binds DNA as a dimer.
      DISEASE: SwissProt: P20823 # Defects in HNF1A may predispose to hepatic adenomas [MIM:142330]. Hepatic adenomas are benign tumors at risk of malignant transformation. Bi-allelic inactivation of HNF1A, whether sporadic or associated with MODY3, may be an early step in the developmant of some hepatocellular carcinomas. & Defects in HNF1A are the cause of maturity onset diabetes of the young type 3 (MODY3) [MIM:600496]; also symbolized MODY-3. MODY [MIM:606391] is a form of diabetes characterized by an autosomal dominant mode of inheritance, age of onset of 25 years or younger and a primary defect in insulin secretion. The clinical phenotype of MODY3 is characterized by severe insulin secretory defects, and by major hyperglycemia associated with microvascular complications. & Defects in HNF1A are a cause of susceptibility to insulin-dependent diabetes mellitus (IDDM) [MIM:222100].
      SIMILARITY: SwissProt: P20823 ## Belongs to the HNF1 homeobox family. & Contains 1 homeobox DNA-binding domain.
