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.

Sequence caution

The sequence AAC24083.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence AAC49696.1 differs from that shown. Reason: Erroneous initiation.
