  2. The myeloproliferative neoplasms (MPNs) patients carrying Calreticulin(CALR) mutations presented with higher platelet counts and lower hemoglobin (show HBB Proteins) levels compared to those with mutated JAK2 (show JAK2 Proteins). However, all of the leukemia patients had negative results for CALR mutations.

  3. Alterated IQGAP1/Rho GTPase (show RACGAP1 Proteins) signaling in myeloproliferative neoplasm erythrocytes is dependent on JAK2 (show JAK2 Proteins)/CALR mutational status.

  4. Recurrent somatic mutations in calreticulin (CALR) gene that encodes a molecular chaperone (show HSP90AA1 Proteins) residing in the endoplasmic reticulum were identified in 2013 in a subset of patients with myeloproliferative neoplasms (MPNs).

  5. These results indicate that mutant CALR causes myeloproliferation because of the activation of JAK (show JAK3 Proteins)-STAT (show STAT1 Proteins) pathway and not by the inhibition of phagocytosis, which is similar to the myeloproliferation caused by JAK2 (show JAK2 Proteins) V617F mutation.

  6. our studies demonstrate that occasional patients with CALR mutation-positive ET or MF carry other MPN (show PRSS27 Proteins)-initiating genetic mutations (including JAK2 (show JAK2 Proteins) V617F), acquire "secondary mutations" before or after the CALR mutation, or evolve over time to being CALR mutation-homozygous.

  7. The meta-analysis of the different populations (including Asian, European, North American and Australian) showed that CALR mutation may increase the prevalence of patients with essential thrombocythemia (19%) and primary myelofibrosis (22%).

  8. CALR- and JAK2 (show JAK2 Proteins)-mutated MPNs are broadly similar in terms of the quantity, frequency and spectrum of co-occurring mutations and therefore observed biological differences are likely to not be heavily influenced by the nature and quantity of co-mutated genes.

  9. The family with JAK2 (show JAK2 Proteins) G571S mutations reported here teaches us that 1 germline JAK2 (show JAK2 Proteins) mutation may hide a somatic CALR mutation, and that, in this case, the phenotype (thrombocytosis) and disease (essential thrombocythemia [ET]) are likely due to the somatic CALR mutation. This highlights the complexity of making the diagnosis of ET (vs. HT) in a familial context.

  10. From included 1138 patients vascular risk patients, 18 individuals were tested positive for the JAK2 (show JAK2 Proteins) V617F mutation. CALR exon 9 mutations were not detected in any of our patients. CALR exon 9 mutations are infrequent in vascular risk patients.

  1. a profound impairment in calreticulin function when its lectin site was inactivated. Remarkably, inactivation of the polypeptide binding site had little impact.

  4.

Pig (Porcine) Calreticulin (CALR) interaction partners

  1. Calreticulin is confined to subplasmalemmal vesicles partially overlapping with cortical granule contents. Its exocytosis after the oocyte activation seems to participate in the membrane block to polyspermy in pigs.

  2. Calreticulin was widely expressed in pig tissues and its transcripts were downregulated during maturation, especially at 44 hr, and were undetectable at the blastocyst stage.

Calreticulin (CALR) Protein Profile

Protein Summary

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.
