Protein

Calreticulin

Gene

Os07g0246200

Organism
Oryza sativa subsp. japonica (Rice)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

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).By similarity

Domaini

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).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
