General description

CALB2 (calbindin 2) gene encodes a calcium-binding protein belonging to the troponin C superfamily. It is also called as calretinin. Structurally, members of this family consists of six EF-hand domains that bind to calcium. It has a molar mass of 29kDa. It is predominantly expressed by certain cells in the nervous system and also in ovarian cells. It is abundantly expressed in colon carcinomas. The gene is localized to human chromosome 16q22.2.

Immunogen

Calretinin 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

CALB2 (calbindin 2) gene encodes a protein that functions in modulating neuronal excitability and also induces apoptosis through the intrinsic mitochondrial pathway. It is involved in several cellular processes, including message targeting and intracellular calcium buffering. It serves as a diagnostic marker for Hirschsprung disease and some cancers. It also serves as a marker for mesothelial differentiation.

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.

The genes encoding calbindin D28k (CALB1) and calretinin (CALB2), two closely related calcium-binding proteins, were mapped by in situ hybridization to the 8q21.3----q22.1 and 16q22----q23 regions of the human genome, respectively. These localizations match the chromosomal regions where the carbonic
