Gene Information
human ... BCAR3(8412)
General description
BCAR3 (breast cancer anti-estrogen resistance 3) belongs to the SH2 domain-containing protein (NSP) family. In humans, this family contains three members namely, NSP1, NSP2/BCAR3 and NSP3. BCAR3 shows high homology to Cdc25 family of Rac GEFs, and contains a GEF (GDP-exchange factor)-like domain in its C-terminal. It also contains an SH2 domain, and a proline/serine-rich domain. It was first described in two estrogen-dependent human breast cancer cell lines, as the gene responsible for anti-estrogen resistance. It has a molecular weight of 95kDa.

Application
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions
BCAR3 (breast cancer anti-estrogen resistance 3) is up-regulated in breast cancers, and is related to invasive and advanced breast cancer type. It facilitates advancement of breast cancer, by activating intracellular signaling pathways essential for metastasis. It is an interacting partner of p130Cas, which in turn activates Rac1. It regulates cell survival, proliferation and movement, by facilitating the interaction between Cas and the protein tyrosine kinase c-Src. It facilitates the progression of cell cycle by interacting with epidermal growth factor (EGF) through its SH2 domain. It promotes cell division in normal human breast MCF-12A cells. It is responsible for anti-estrogen resistance in breast cancer cells by activating PI3K (phosphatidylinositol 3-kinase), which in turn activates Rac pathway.
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.

NSP protein family members associate with p130Cas, a focal adhesion adapter protein best known as a Src substrate that integrates adhesion-related signaling. Over-expression of AND-34/BCAR3/NSP2 (BCAR3), but not NSP1 or NSP3, induces anti-estrogen resistance in human breast cancer cell lines.
