CALR (Calreticulin) is a gene. The public catalogues list it as a drug target, a biomarker and a fusion partner, and an approved or late-stage drug is recorded against it. Tied to Myeloproliferative neoplasms, Essential thrombocythaemia and Primary myelofibrosis. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

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 synthesised 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. Location: Endoplasmic reticulum lumen; Cytoplasm, cytosol; Secreted, extracellular space, extracellular matrix; Cell surface (UniProt). Locus 19p13.13 (HGNC).
