PDIA3 Antibody (Center)

Purified Rabbit Polyclonal Antibody (Pab)

     
  • 1 - PDIA3 Antibody (Center) AP2922c
    Western blot analysis of PDIA3 Antibody (Center) (Cat. #AP2922c) in A2058, A375, Ramos cell line lysates (35ug/lane). PDIA3 (arrow) was detected using the purified Pab.(2ug/ml)
  • 1 - PDIA3 Antibody (Center) AP2922c
    Western blot analysis of PDIA3 (arrow) using rabbit polyclonal PDIA3 Antibody (Center) (Cat. #AP2922c). 293 cell lysates (2 ug/lane) either nontransfected (Lane 1) or transiently transfected with the PDIA3 gene (Lane 2) .
  • 14 - PDIA3 Antibody (Center) AP2922c
    Formalin-fixed and paraffin-embedded human lung carcinoma reacted with PDIA3 Antibody (Center), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.
  • 4 - PDIA3 Antibody (Center) AP2922c
    Flow cytometric analysis of widr cells using PDIA3 Antibody (Center)(bottom histogram) compared to a negative control cell (top histogram)FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.

Protein Information
Name PDIA3 (HGNC:4606)
Synonyms ERP57, ERP60, GRP58
Function Protein disulfide isomerase that catalyzes the formation, isomerization, and reduction or oxidation of disulfide bonds in client proteins and functions as a protein folding chaperone (PubMed:11825568, PubMed:16193070, PubMed:27897272, PubMed:36104323, PubMed:7487104). Core component of the major histocompatibility complex class I (MHC I) peptide loading complex where it functions as an essential folding chaperone for TAPBP. Through TAPBP, assists the dynamic assembly of the MHC I complex with high affinity antigens in the endoplasmic reticulum. Therefore, plays a crucial role in the presentation of antigens to cytotoxic T cells in adaptive immunity (PubMed:35948544, PubMed:36104323).
Cellular Location Endoplasmic reticulum. Endoplasmic reticulum lumen {ECO:0000250|UniProtKB:P11598}. Melanosome Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV (PubMed:12643545).
Tissue Location Detected in the flagellum and head region of spermatozoa (at protein level) (PubMed:20400973). Expressed in liver, stomach and colon (at protein level). Expressed in gastric parietal cells and chief cells (at protein level) (PubMed:24188822)

BACKGROUND

PDIA3 is the endoplasmic reticulum that interacts with lectin chaperones calreticulin and calnexin to modulate folding of newly synthesized glycoproteins. The protein was once thought to be a phospholipase; however, it has been demonstrated that the protein actually has protein disulfide isomerase activity. It is thought that complexes of lectins and this protein mediate protein folding by promoting formation of disulfide bonds in their glycoprotein substrates.
