Background of CALR

Calreticulin also known as calregulin, CRP55, CaBP3, calsequestrin-like protein, and endoplasmic reticulum resident protein 60  (ERp60) is a protein that in humans is encoded by the CALR gene. It is mapped to 19p13.13. Calreticulin is a multifunctional protein that acts as a major Ca (2+)-binding (storage) protein in the lumen of the endoplasmic reticulum. It is also found in the nucleus, suggesting that it may have a role in transcription regulation. Calreticulin binds to the synthetic peptide KLGFFKR, which is almost identical to an amino acid sequence in the DNA-binding domain of the superfamily of nuclear receptors. Calreticulin binds to antibodies in certain sera of systemic lupus and Sjogren patients which contain anti-Ro/SSA antibodies, it is highly conserved among species, and it is located in the endoplasmic and sarcoplasmic reticulum where it may bind calcium. The amino terminus of calreticulin interacts with the DNA-binding domain of the glucocorticoid receptor and prevents the receptor from binding to its specific glucocorticoid response element. Calreticulin can inhibit the binding of androgen receptor to its hormone-responsive DNA element and can inhibit androgen receptor and retinoic acid receptor transcriptional activities in vivo, as well as retinoic acid-induced neuronal differentiation. Thus, calreticulin can act as an important modulator of the regulation of gene transcription by nuclear hormone receptors. Systemic lupus erythematosus is associated with increased autoantibody titers against calreticulin but calreticulin is not a Ro/SS-A antigen. Earlier papers referred to calreticulin as an Ro/SS-A antigen but this was later disproven. Increased autoantibody titer against human calreticulin is found in infants with complete congenital heart block of both the IgG and IgM classes.

Question

Our lab used your anti-Calreticulin/CALR antibody for ELISA on brain a few years ago. I am using mouse, and We intend to use the antibody for WB next. I am interested in examining brain as well as keratinocyte in our next experiment. Do you have any suggestion on which antibody would work the best for WB?

Verified Customer

Verified customer

Asked: 2020-04-16

Answer

I have checked the website and datasheets of our anti-Calreticulin/CALR antibody and it seems that A00894-1 has been validated on mouse in both ELISA and WB. Thus A00894-1 should work for your application. Our Boster satisfaction guarantee will cover this product for WB in mouse even if the specific tissue type has not been validated. We do have a comprehensive range of products for WB detection and you can check out our website bosterbio.com to find out more information about them.

Question

We were happy with the WB result of your anti-Calreticulin/CALR antibody. However we have been able to see positive staining in colon carcinoma endoplasmic reticulum lumen using this antibody. Is that expected? Could you tell me where is CALR supposed to be expressed?

Verified Customer

Asked: 2019-11-12

Answer

Based on literature, colon carcinoma does express CALR. Generally CALR expresses in endoplasmic reticulum lumen. Regarding which tissues have CALR expression, here are a few articles citing expression in various tissues:
Colon carcinoma, Pubmed ID: 9150948
Eye, Pancreas, and Skin, Pubmed ID: 15489334
