Biological background
CALR (protein: Glycogen synthase kinase-3 beta (gsk3b)) is a commonly studied target in molecular and cellular biology. Functional context (as provided): 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 (By similarity). . Reported cellular localization context: Endoplasmic reticulum lumen . Cytoplasm, cytosol . Secreted, extracellular space, extracellular matrix . Cell surface . Sarcoplasmic reticulum lumen . Also found in cell surface (T cells), cytosol and extracellular matrix (PubMed:10358038). Associated with the lytic granules in the cytolytic T-lymphocytes. . Tissue expression notes (as provided): Ubiquitous. Highest levels of expression in adult spleen and peripheral blood leukocytes, and in fetal brain, kidney and lung. Isoform 1 is expressed in heart, kidney and liver.
Research relevance and current trends
- Research context keywords from the source record include: Organelle Proteins,Organelles,Protein Trafficking,Signal Transduction,Subcellular Markers,Tags & Cell Markers.
- Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
- Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.
Common research applications
- Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
- Immunohistochemistry (IHC): evaluate spatial distribution of target-positive staining in tissue architecture.
- Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.
- Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.
- Immunoprecipitation (IP): enrich target complexes for downstream immunoblot or interaction analyses.
Workflow ideas (metafield): Validate CALR antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect CALR expression by Western blot in cell or tissue lysates, Detect CALR in FFPE tissue sections by immunohistochemistry, Localize CALR by immunofluorescence/immunocytochemistry in cultured cells, Quantify CALR-positive cells by flow cytometry in single-cell suspensions, Enrich CALR by immunoprecipitation from lysates for downstream analysis
Notes for experimental interpretation
- Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
- Apparent molecular weight may vary by sample type and processing (observed MW: 60 kDa; calculated MW: 48142 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
