General description

Runt-related transcription factor 2/acute myeloid leukemia 3 protein (RUNX2, AML-3) belongs to Runt DNA-binding domain transcription factor family. RUNX2 gene is mapped to human chromosome 6p21.1 RUNX2 possesses the Runt domain, nuclear localization signal (NLS), the nuclear matrix targeting signal (NMTS) and a C-terminal VWRPY sequence. It also has two additional domains, one being the N-terminal glutamine-alanine (QA) repeats and the other a C-terminal proline/serine/threonine (PST) rich tract. RUNX2 exists in two isoforms. The isoform 1 is expressed in osteoblasts and the isoform 2 is distributed in mesenchymal condensations and mature chondrocytes.

Runt-related transcription factor 2/acute myeloid leukemia 3 protein (RUNX2, AML-3) is a Runt DNA-binding domain transcription factor that facilitates osteoblast differentiation and skeletal morphogenesis.


Rabbit polyclonal anti-RUNX2 antibody reacts with human runt-related transcription factor 2/Acute myeloid leukemia 3 protein.


Runt-related transcription factor 2 recombinant protein epitope signature tag (PrEST)


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. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Anti-RUNX2 antibody produced in rabbit has been used in immunohistochemistry and immunofluorescence.

Rabbit polyclonal anti-RUNX2 antibody is used to tag Runt-related transcription factor 2/Acute myeloid leukemia 3 protein for detection and quantitation by immunocytochemical and immunohistochemical (IHC) techniques. It is used as a probe to determine the presence and roles of runt-related transcription factor 2/Acute myeloid leukemia 3 protein in osteoblast differentiation and skeletal morphogenesis.

Biochem/physiol Actions

Runt-related transcription factor 2/ acute myeloid leukemia 3 protein (RUNX2, AML-3) mediates osteoblast differentiation and skeletal morphogenesis. It promotes mesenchymal cell differentiation in osteoblasts and its maturation. Elevated levels of RUNX2 is observed in bone?metastatic cancers. The post-translational modifications like phosphorylation, methylation, glycosylation and ubiquitination in the RUNX2 modulates osteogenesis. Mutations in the RUNX2 gene leading to loss of function is implicated in cleidocranial dysplasia (CCD). The levels of RUNX2 is elevated in osteosarcoma.

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 APREST86701.
