Recombinant Human CALR Protein(HEK293)，His

Calreticulin (CALR) is a multi-functional protein that plays a crucial role in calcium homeostasis, protein folding, and quality control within the endoplasmic reticulum (ER). Recent studies have highlighted its significant involvement in various hematological malignancies, particularly those associated with mutations in the CALR gene, which have been identified as a key driver of myeloproliferative neoplasms (MPNs). These mutations typically lead to a gain-of-function effect, altering the protein's interaction with calcium and the ER stress response, thus promoting abnormal cell proliferation. The search for CALR's specific contributions to oncogenesis has driven researchers to investigate recombinant CALR proteins, employing techniques such as expression cloning and yeast or bacterial systems to purify these variants. Such studies aim to elucidate the structural and functional characteristics of wild-type and mutant CALR proteins, as well as their potential as therapeutic targets. Additionally, the recombinant CALR provides a valuable tool for developing cellular and animal models to better understand its role in disease mechanisms. As therapeutic approaches evolve, understanding CALR's molecular pathways may identify new strategies for targeted treatment and improve prognosis for patients with CALR-associated myeloproliferative disorders. Therefore, research on recombinant CALR is critical for advancing our knowledge of its biological functions and implications in cancer biology, particularly within the context of MPNs.
