The multifunctional, multi -compartmental protein Calreticulin (Crt) functions as a soluble molecular chaperone of new or misfolded proteins, as well as a Ca2+-binding protein. Most abundant in the ER lumen, Crt expression also occurs in other membrane-bound organelles, the cell surface, and extracellularly. Also known as CRP-55, calregulin and HACBP (high affinity calcium-binding protein), Crt contains the ER-retrieval sequence, KDEL, and is the solub le paralog of the ER membrane protein Calnexin (Cnx). Crt's three domains include a 180 residue N-terminal domain, a proline-rich Pdomainresidues 189 -288) that binds Ca2+ with high affinity and shares homology with Cnx and calmegin, and a 110 residue C-terminal domain that binds Ca2+ with low affinity but high capacity. The P-domain may interact with the co-chaperone ERp57 (Grp58), a thiol reductase. The NMR structure of the P -domain consists of an extended hairpin that appears to form a curved protrusion from the Crt core domain. Both Crt and its membrane bound homolog CNX interact with proteins and glycoproteins possessing monoglucosylated N -glycans. The Crt/Cnx cycle promotes correct folding, inhibits aggregation of folding intermediates, blocks premature oligomerization, regulates ER degradation, and prevents incompletely folded glycoproteins from exiting to the Golgi complex. Crt also appears to function as an auto-antigen in systemic lupus erythematosus, rheumatoid arthritis, celiac disease, complete congenital heart block, and halothane hepatitis. A diversity of additional functions attributed to Crt includes adhesion, blood function, and cardiac and neuronal development gene expression.

多功能、多區室蛋白鈣網蛋白（Crt）可作為新的或錯誤折疊的蛋白質的可溶性分子伴侶，以及Ca2+結合蛋白。Crt 表達在 ER 管腔中最為豐富，也發生在其他膜結合細胞器、細胞表面和細胞外。Crt 也稱為 CRP-55、鈣調節蛋白和 HACBP（高親和力鈣結合蛋白），含有 ER 檢索序列 KDEL，是 ER 膜蛋白鈣連接蛋白 （Cnx） 的可溶物。

CRT 似乎也可作為系統性紅斑狼瘡、類風濕性關節炎、乳糜瀉、完-全性先天性心臟傳導阻滯和氟烷肝炎的自身抗原發揮作用。Crt 的多種附加功能包括粘附、血液功能以及心臟和神經元發育基因表達。
