Background: CC1qR,CRT,HEL-S-99n,RO,SSA
Calreticulin is a highly conserved chaperone protein which resides primarily in the endoplasmic reticulum, and is involved in a variety of cellular processes, among them, cell adhesion. Additionally, it functions in protein folding quality control and calcium homeostasis. Calreticulin is also found in the nucleus, suggesting that it may have a role in transcription regulation. Systemic lupus erythematosus is associated with increased autoantibody titers against calreticulin. Recurrent mutations in calreticulin have been linked to various neoplasms, including the myeloproliferative type.[provided by RefSeq, May 2020]

Molecular Weight: predicted molecular mass of 47.3 kDa after removal of the signal peptide.The apparent molecular mass of CALR-His is 55-70 kDa due to glycosylation.
