  • Function
    Essential oxidoreductase that oxidizes proteins in the endoplasmic reticulum to produce disulfide bonds. Acts by oxidizing directly P4HB/PDI isomerase through a direct disulfide exchange. Does not act as a direct oxidant of folding substrate, but relies on P4HB/PDI to transfer oxidizing equivalent. Associates with ERP44 but not with GRP54, demonstrating that it does not oxidize all PDI related proteins and can discriminate between PDI and related proteins. Its reoxidation probably involves electron transfer to molecular oxygen via FAD. Acts independently of glutathione. May be responsible for a significant proportion of reactive oxygen species (ROS) in the cell, thereby being a source of oxidative stress. Required for the folding of immunoglobulin proteins. Responsible for the release of the unfolded cholera toxin from reduced P4HB/PDI in case of infection by V.cholerae, thereby playing a role in retrotranslocation of the toxin.
  • Tissue specificity
    Widely expressed at low level. Expressed at high level in upper digestive tract. Highly expressed in esophagus. Weakly expressed in stomach and duodenum.
  • Sequence similarities
    Belongs to the EROs family.
  • Post-translational
    The Cys-94/Cys-99 and Cys-394/Cys-397 disulfide bonds constitute the redox-active center. The Cys-94/Cys-99 disulfide bond may accept electron from P4HB and funnel them to the active site disulfide Cys-394/Cys-397.
  • Cellular localization
    Endoplasmic reticulum membrane. The association with ERP44 is essential for its retention in the endoplasmic reticulum.

  • Anti-ERO1L antibody (ab81959) at 1/1000 dilution + 293T cell lysate

    Predicted band size: 54 kDa
    Observed band size: 54 kDa

    ab81959 appears to run as a doublet believed to represent the oxidized and reduced forms of the protein.

Thank you for providing that information.

As I mentioned previously, with the exception of ab79483, we do guarantee that these antibodies should work in western blot on rat tissue. If we cannot resolve the issue you are having with the antibod...

Thank you for contacting Abcam.

I am sorry that you are having some issues with our antibodies. All of the antibodies you mentioned should work in western blot in various species, however only ab30315 is known to work in IHC-P. Below is a list...
