  • Function
    Acts as an intracellular estrogen-binding protein. May be involved in modulating cellular levels and biological functions of estrogens in the pancreas. May act as a chaperone that inhibits aggregation of misfolded proteins.
  • Tissue specificity
    Highly expressed in pancreas (at protein level).
  • Sequence similarities
    Belongs to the protein disulfide isomerase family.
    Contains 2 thioredoxin domains.
  • Post-translational
    The disulfide-linked homodimer exhibits an enhanced chaperone activity.
  • Cellular localization
    Endoplasmic reticulum lumen.

Thank you for contacting us.

Regrettably, we will not be able to guarantee the anti PDI antibodies cross reactivity towards P. pastoris species. The sequence analysis of ab30319 shows only 45% homology which is very less for antibody cross reactivity. I apologies for any inconvenience.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
