Protein
Calreticulin
Gene
crtA, DDB_G0283539
Organism
Dictyostelium discoideum (Slime mold)
Status
Reviewed - Annotation score: 4 out of 5 - 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.

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.
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.
