NCIt definition : Calreticulin (417 aa, 48 kDa) is encoded by the human CALR gene. This protein plays
a role in protein folding.;
NCIt note : Increased titers of autoantibodies to calreticulin are found in systemic lupus erythematosus
and in infants with complete congenital heart block. Older reports referred to calreticulin
as an Ro/SS-A antigen but this was later disproven. (Entrez Gene and UniProt);
