Mutations of the gene coding for calreticulin (CALR) that cause the loss of the C-terminal KDEL motif abolish its retention in the endoplasmic reticulum and cause CALR to be secreted from cells. Specific CALR mutants bearing a novel C-terminus can precipitate the manifestation of myeloproliferative diseases via the autocrine activation of the thrombopoietin receptor.
