產品描述：

This Recombinant Mouse Calr protein was made through genetic engineering. By putting the Calr gene into the genetic material of E.coli cell, the E.coli could be used as factories or producers to make the desired Calr protein for research uses. The expression region of this protein is at 18-416aa. N-terminal GST tag was used in the expression process. The purity is 90%+ determined by SDS-PAGE.
Calreticulin (CALR) is a Ca2+-binding endoplasmic reticulum (ER) protein that aids the folding of proteins destined to secretion and insertion in the plasma membrane, de facto providing a major contribution to the maintenance of cellular homeostasis when unfolded proteins accumulate within the ER (e.g., in the context of viral infection). Moreover, CALR mechanistically contributes to the initiation of adaptive anticancer immunity in the context of immunogenic cell death (ICD), a functional variant of regulated cell death (RCD) that is sufficient to elicit an antigen-specific immune response in immunocompetent, syngeneic hosts (provided that dying cells express antigens not covered by central or peripheral tolerance). In particular, CALR exposed on the surface of cancer cells undergoing ICD mediates robust pro-phagocytic effects, hence facilitating the uptake of dying cells or their corpses by antigen-presenting cells (APCs), in particular immature dendritic cells (DCs), which migrate to lymph nodes to cross-prime tumors specific na?ve CD8+ T cells.

靶點詳情

功能：

Calcium-binding chaperone that promotes folding, oligomeric assembly and quality control in the endoplasmic reticulum (ER) via the calreticulin/calnexin cycle. This lectin interacts transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER. Interacts with the DNA-binding domain of NR3C1 and mediates its nuclear export. Involved in maternal gene expression regulation. May participate in oocyte maturation via the regulation of calcium homeostasis. Present in the cortical granules of non-activated oocytes, is exocytosed during the cortical reaction in response to oocyte activation and might participate in the block to polyspermy.
