  • Function
    Molecular 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 similarities
    Belongs to the calreticulin family.
  • 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.
    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 localization
    Endoplasmic 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.

ab22683's immunogen was Calreticulin-maltose binding fusion protein. I am very sorry but we have not done epitope mapping for this antibody and therefore cannot confirm exactly where it binds so unfortunately I cannot say whether it will recognise you...
