Protein

Calreticulin

Gene

CAL1

Organism
Nicotiana plumbaginifolia (Leadwort-leaved tobacco) (Tex-Mex tobacco)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript 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

Sequence similaritiesi

Belongs to the calreticulin family.Curated
