Automated description from the Alliance of Genome Resources (Release 7.0.0)
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. 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).
