ANTI-CBLB (C15-1448-995)

General description

The gene casitas B-lineage lymphoma proto-oncogene b (CBLB) is mapped to human chromosome 3q13.11. It belongs to CBL family of ubiquitin ligases.

Immunogen

E3 ubiquitin-protein ligase CBL-B recombinant protein epitope signature tag (PrEST)

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

Casitas B-lineage lymphoma proto-oncogene b (CBLB) is phosphorylated upon T cell receptor (TCR) stimulation and is involved in TCR-mediated intracellular signaling pathways. Similarly, phosphorylated CBLB is recruited to epidermal growth factor receptor (EGFR) upon EGF stimulation and inhibits EGF-induced cell growth. CBLB interacts with CIN85 (SH3 domain-containing kinase-binding protein 1) and together they regulate EGF receptor endocytosis and down-regulation of the activated receptor. CBLB participates in controlling T-cell activation thresholds by negative regulation of Vav, a GDP/GTP exchange factor. The molecular mechanism involves CBLB-mediated degradation of p85 regulatory subunit of phosphatidylinositol 3-kinase, an upstream regulator of Vav. CBLB is associated with an autoimmune disease of the central nervous system, multiple sclerosis.

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.

Linkage
