Gene Information

human ... CBLL1(79872)

General description

CBLL1 (Cbl proto-oncogene-like 1, E3 ubiquitin protein ligase) is a cbl-like ubiquitin ligase of E-cadherin complex. It is expressed in the neurons of central nervous system.

Biochem/physiol Actions

CBLL1 (Cbl proto-oncogene-like 1, E3 ubiquitin protein ligase) is an E-cadherin binding protein involved in the ubiquitination of E-cadherin and regulation of E-cadherin complex endocytosis. During ubiquitination, it directly binds to the cytoplasmic domain of E-cadherin. It has been reported in a study that CBLL1 may play a role in neuronal apoptosis and in LPS (Lipopolysaccharide) administration. CBLL1 also have been predicted as a regulator of cell proliferation.

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 APREST74889.

Physical form

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

Studies have shown that E3 ubiquitin ligase CBLL1 plays multiple roles in development and tumorigenesis. CBLL1 is over-expressed in colon cancer and associated with cancer cell proliferation. While, the overexpression of CBLL1 inhibited the estrogenic dependent cell proliferation and migration...

CBLL1 (Casitas B-lineage lymphoma-transforming sequence-like protein 1) also known as Hakai, was originally identified as an E3 ubiquitin-ligase for the E-cadherin complex. Recent data have provided evidences for novel biological functional role of CBLL1 during tumor progression and other diseases....
