Summary: Enables calcium ion binding activity; carbohydrate binding activity; and mRNA binding activity. Involved in several processes, including peptide antigen assembly with MHC class I protein complex; positive regulation of phagocytosis; and protein stabilization. Acts upstream of or within cortical actin cytoskeleton organization; positive regulation of non-canonical NF-kappaB signal transduction; and regulation of meiotic nuclear division. Located in endoplasmic reticulum; external side of plasma membrane; and extracellular space. Part of MHC class I peptide loading complex. Is expressed in several structures, including central nervous system; extraembryonic component; gut; placenta; and white fat. Used to study congestive heart failure. Human ortholog(s) of this gene implicated in several diseases, including endocrine gland cancer (multiple); gastrointestinal system cancer (multiple); hematologic cancer (multiple); lung cancer (multiple); and thrombocytosis. Orthologous to human CALR (calreticulin). [provided by Alliance of Genome Resources, May 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
