Description

General description

The gene for calreticulin (CALR) is located on the human chromosome 19p13.13. The encoded protein is a predominantly conserved calcium-binding chaperone, which is localized primarily to the lumen of the endoplasmic reticulum (ER). Calreticulin comprises three domains, a globular N-domain, a proline-rich P-domain, and a highly acidic C-domain.

Immunogen

synthetic peptide corresponding to the C-terminus of human calreticulin (amino acids 401-417).

Application

Anti-Calreticulin antibody produced in rabbit has been used in:

• immunoblotting[1]
• immunofluorescence[2]
• immunocytochemistry{91
• immunoprecipitation

Biochem/physiol Actions

Anti-Calreticulin recognizes human and dog calreticulin (55-60 kDa).

Calreticulin facilitates transient interaction with newly synthesized cellular and extracellular proteins for folding and assembling in the endoplasmic reticulum (ER) before its localization to the cytosol or cell surface. Calreticulin acts as a lectin-like chaperone binding oligosaccharide residues of newly synthesized N-linked glycoproteins and misfolded proteins. It is believed to play a critical role in quality control processes during protein synthesis and folding and calcium (Ca²⁺) homeostasis. Increased expression of calreticulin increases the Ca²⁺ storage capacity of the ER. It also appears to modulate store-operated Ca²⁺-influx and to alter Ca²⁺ transport by the sarcoplasmic/ER Ca²⁺-adenosine triphosphatase (ATPase) (SERCA). Overexpression of calreticulin results in increased sensitivity of HeLa cells to drug-induced apoptosis. However, increased resistance to apoptosis has been observed in calreticulin-deficient cells.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Preparation Note

Store at -20 °C. For continuous use, the product maybe stored at 2-8 °C for up to one month. For prolonged storage, freeze in working aliquots at-20 °C. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded ifnot used within 12 hours.
