Anti-LRBA antibody produced in rabbit

Lrba consists of a BEACH domain situated between a PH-like domain and WD-40 domain.

The gene LRBA (lipopolysaccharide-responsive and beige-like anchor protein) is mapped to human chromosome 4q31.3. It belongs to the BEACH (beige and chediak-higashi)-WD40 (β-transducin) protein family. LRBA is ubiquitously expressed. The protein localizes in the cytoplasm. Upon activation of B cells, LRBA moves to the membrane of trans-Golgi network, lysosomes, endoplasmic reticulum and to the cell surface.

Anti-LRBA antibody produced in rabbit has been used:

• in western blotting
• fluorescence-activated cell sorting (FACS)
• basic Local Alignment Search Tool (BLAST) analysis,
• flow cytometry analysis

Anti-LRBA 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.

LRBA (lipopolysaccharide-responsive and beige-like anchor protein) participates in endocytosis of ligand-activated receptors. Mutations in LRBA are linked with inflammatory bowel disease (IBD)-like symptoms, autoimmune lymphoproliferative syndrome-like disease and IPEX (immune dysregulation, polyendocrinopathy, enteropathy, X-linked) syndrome.

Lrba interacts with protein kinase A and modulates the intracellular vesicle trafficking to activated receptor complexes. This aids the secretion and membrane deposition of immune effector molecules, like cytotoxic T lymphocyte-associated antigen‐4 (CTLA4). The PH-like domain is critical for membrane association and WD-40 domain helps in ligand binding and signaling.

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.
