General description

CBLB (Cbl proto-oncogene B) is an E3 ubiquitin protein ligase belonging to the CBL protein family. It is mapped to human chromosome 3q13.11. In mammals, there are three homologues of Cbl, namely c-Cbl, Cbl-b and Cbl-c. It is composed of highly conserved tyrosine kinase binding (TKB) domain and new gene (RING) finger catalytic domains.

Immunogen

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

Application

Anti-CBLB 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

CBLB (Cbl proto-oncogene B) plays a crucial role in the regulation of immune cell activation. Both the domains perform different activities in ubiquitin ligase activity, such as TKB domain interacts directly with phosphorylated tyrosine-containing proteins through Src homology (SH) 2 domains and RING finger domain binds to E2 ubiquitin-conjugating. CBLB is phosphorylated upon T cell receptor (TCR) stimulation and is involved in TCR-mediated intracellular signaling pathways enzymes. Similarly, phosphorylated CBLB is recruited to epidermal growth factor receptor (EGFR) upon EGF stimulation and inhibits EGF-induced cell growth. 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.
