General description
UBTF (upstream binding transcription factor) is composed of six HMG box domains, which are lined up consecutively. It also contains a dimerization and a transactivation domain. It has two isoforms- UBF1 and UBF2. It is also called NOR (nucleolus organizer region)-90, and is a member of the NOR family, which is a family of ribosomal genes. It is highly expressed in human fetus. This gene is localized to human chromosome 17q21.3.

Application
Anti-UBTF antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem/physiol Actions
UBTF (upstream binding transcription factor) or NOR-90 is a transcriptionally competent NOR as it is active during interphase. It serves as a scaffold to conform chromatin in a transcriptionally favorable condition. It is involved in the transcription of rDNA (ribosomal DNA), when it interacts with Pol I (RNA polymerase 7) enzyme. Along with SL1 (selectivity factor 1) complex, it binds to the enhancer region of rDNA. It acts as a negative regulator of Herpes simplex virus 1 (HSV-1) replication, where it suppresses the expression of viral DNA. It plays a role in tissue development and leukemia development.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

To maintain growth and division, cells require a large-scale production of rRNAs which occurs in the nucleolus. Recently, we have shown the interaction of nucleolar phosphatidylinositol 4,5-bisphosphate (PIP2) with proteins involved in rRNA transcription and processing, namely RNA polymerase I

Previous reports have shown that adenovirus recruits nucleolar protein upstream-binding factor (UBF) into adenovirus DNA replication centres. Here, we report that despite having a different mode of viral DNA replication, herpes simplex virus type 1 (HSV-1) also recruits UBF into

Ribosomal genes are organized in clusters termed Nucleolus Organizer Regions (NORs). Essential components of the RNA polymerase I transcription machinery, including Upstream Binding Factor (UBF), can be detected on some NORs during mitosis; these NORs, termed competent, are believed to

During Pol I-mediated rRNA synthesis, UBF plays a key role in transcription. Numerous localization studies provided, however, rather divergent results with regard to its presence in either of the two structural nucleolar subcompartments, FC and DFC. These observations suggest different

The 90-kDa nucleolus organizer region autoantigen (NOR-90) was previously shown to be identical to human upstream binding factor (hUBF), which has two molecular mass forms of 89 and 93 kDa, respectively. hUBF/NOR-90 is a member of the HMG-box DNA-binding protein
