    • Relevance
      Proper protein folding and post-translational modifications are essential for secretory protein export out of the endoplasmic reticulum. This task is accomplished by chaperone proteins such as protein disulfide isomerase (PDI), GRP94, and BiP. A recently characterized protein, designated ERp29, is closely related to these chaperone proteins and appears to be upregulated during ER stress conditions. ERp29 is a soluble 259-residue protein that is localized to the lumen of the endoplasmic reticulum in all mammalian cells. Research has shown that there are two primary domains within ERp29. The first is the C-terminal region that is a novel, all helical, fold that is most likely involved with ERp29 retention to the ER. The second is the N-terminal region that resembles that of PDI’s thioredoxin module. The protein shows sequence similarity to the protein disulfide isomerase family. However, it lacks the thioredoxin motif characteristic of this family, suggesting that this protein does not function as a disulfide isomerase. The protein dimerizes and is thought to play a role in the processing of secretory proteins within the ER.

    • Anti-ERp29 antibody (ab37850) at 1/2000 dilution + E. coli-derived fusion protein.

      Goat anti-IgY-HRP at 1/1000

      Predicted band size: 29 kDa
      Observed band size: 75 kDa
      why is the actual band size different from the predicted?
      Additional bands at: 40 kDa (possible non-specific binding), 40 kDa (possible degradation product), 45 kDa (possible non-specific binding), 45 kDa (possible degradation product), 60 kDa (possible non-specific binding), 60 kDa (possible degradation product)

      The actual band size differs from the observed size as this Western blot used a fusion protein as test antigen.
