Probably plays a role in facilitating the assembly of multimeric protein complexes inside the endoplasmic reticulum. Involved in the correct folding of proteins and degradation of misfolded proteins via its interaction with DNAJC10, probably to facilitate the release of DNAJC10 from its substrate.
Involvement in disease
Autoantigen in rheumatoid arthritis.
Belongs to the heat shock protein 70 family.
Endoplasmic reticulum lumen. Melanosome. Cytoplasm. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
IHC image of GRP78 BiP staining in XHuman breast fibroadenoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol B. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab25192, 10µg/ml, for 15 mins at room temperature. A Goat anti-Rat biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
Western blot - Anti-GRP78 BiP antibody [76-E6] (ab25192)
Predicted band size : 72 kDa
Total cell lysates from Ag8.653 cells were resolved by electrophoresis, transferred to PVDF membrane, and probed with Anti-GRP78 BiP antibody [76-E6] ab25192 (2 µg/mL). Proteins were visualized using Goat Anti-Rat Ig, Mouse ads-HRP secondary antibody and chemiluminescent detection.
