Gene Information

human ... ZBTB7B(51043)

General description

ZBTB7B (zinc finger and BTB domain containing 7B) is a zinc finger-containing transcription factor belonging to the early growth response gene family. It is expressed in the foreskin and dermal fibroblasts. It consists of three kruppel-like zinc-finger DNA binding domains, a POZ (poxvirus and zinc finger) domain for the transcriptional repression and protein dimerization.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem/physiol Actions

ZBTB7B (zinc finger and BTB domain containing 7B) is highly essential for the CD4+ commitment and prevention of CD8+ commitment. ZBTB7B plays an important role in the development of T cell subsets such as double-negative invariant natural killer T (iNKT) cells, γδ cells, and memory CD8+ T cells. It also represses collagen transcription by binding to the α1 and α2 collagen gene promoters directly. It has been reported that ZBTB7B may play a role in the repression of fibronectin and other matrix genes.

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:
  • 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.


Corresponding Antigen APREST70952.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
