      Brand Family Upstate
      Trade Name
      • Upstate
      Description TOPflash (TCF Reporter Plasmid)
      Product Information
      Application Transfection grade T-cell factor reporter plasmid containing 2 sets (with
      the second set in the reverse orientation) of 3 copies of the TCF binding site (wild type) upstream of the Thymidine Kinase minimal promoter and
      Luciferase open reading frame.
      Key Applications
      • Transfection
      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.
