General annotation (Comments)
| Function | Molecular calcium binding chaperone promoting folding, oligomeric assembly and quality control in the ER via the calreticulin/calnexin cycle. This lectin interacts transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER. Interacts with the DNA-binding domain of NR3C1 and mediates its nuclear export By similarity. |
| Subunit structure | Monomer. Component of an EIF2 complex at least composed of CUGBP1, CALR, CALR3, EIF2S1, EIF2S2, HSP90B1 and HSPA5. Interacts with PDIA3/ERp57 and with NR3C1 By similarity. |
| Subcellular location | |
| Tissue specificity | Predentin and odontoblast. |
| Domain | Can be divided into a N-terminal globular domain, a proline-rich P-domain forming an elongated arm-like structure and a C-terminal acidic domain. The P-domain binds one molecule of calcium with high affinity, whereas the acidic C-domain binds multiple calcium ions with low affinity By similarity. The interaction with glycans occurs through a binding site in the globular lectin domain By similarity. The zinc binding sites are localized to the N-domain By similarity. Associates with PDIA3 through the tip of the extended arm formed by the P-domain. |
| Sequence similarities | Belongs to the calreticulin family. |
| Caution | Was originally (Ref.9) thought to be D-beta-hydroxybutyrate dehydrogenase. |
