  • FunctionMolecular calcium-binding chaperone promoting folding, oligomeric assembly and quality control in the ER via the calreticulin/calnexin cycle. This lectin interacts transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER. Interacts with the DNA-binding domain of NR3C1 and mediates its nuclear export.
  • Sequence similaritiesBelongs to the calreticulin family.
  • DomainCan 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.
    The interaction with glycans occurs through a binding site in the globular lectin domain.
    The zinc binding sites are localized to the N-domain.
    Associates with PDIA3 through the tip of the extended arm formed by the P-domain.
  • Cellular localizationEndoplasmic reticulum lumen. Cytoplasm > cytosol. Secreted > extracellular space > extracellular matrix. Cell surface. Also found in cell surface (T cells), cytosol and extracellular matrix. Associated with the lytic granules in the cytolytic T-lymphocytes.

Thank you for contacting us.

Yes, this is the full length protein. For full length proteins we have left the start and stop amino acids as 0, since there is not a start and stop like there is for a peptide.

I hope this infor...
