ab2907 used at a 1/1000 dilution staining Calreticulin in HeLa cells by Immunocytochemistry/ Immunofluorescence.

HeLa cells were transfected overnight with empty vector or plasmids encoding the indicated IFITM3 constructs. Immunofluorescence with a-HA antibodies allowed IFITM3 visualization, and a-calreticulin staining allowed visualization of the ER. TOPRO-3 was used to visualize nuclei. Scale bars indicate 10 µm. UbΔ indicates mutation of Lys-24, Lys-83, Lys-88, and Lys-104 to alanine.

Calreticulin (CALR, HACBP) is a multifunctional protein involved in protein folding and calcium homeostasis within the endoplasmic reticulum. In oncology, it plays a crucial role in immunogenic cell death by acting as a signal for immune cells to target and destroy cancer cells. Calreticulin (CALR, HACBP) is also implicated in tumor progression and metastasis due to its role in cell adhesion and migration. As a result, it is being explored as a potential therapeutic target for cancer treatment.

Target data

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 (PubMed : 7876246). Interacts with the DNA-binding domain of NR3C1 and mediates its nuclear export (PubMed : 11149926). Involved in maternal gene expression regulation. May participate in oocyte maturation via the regulation of calcium homeostasis (By similarity). 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 (By similarity).
