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 may interact transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER By similarity. |
| Subcellular location | Endoplasmic reticulum lumen By similarity. |
| 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. |
| Sequence similarities | Belongs to the calreticulin family. |
