ab3674 (1/1000) staining GPR94 in human stomach using an automated system (DAKO Autostainer Plus). Using this protocol there is strong cytoplasmic staining of peptic and parietal cells of the gastric gland.
Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

The cells were permeabilized with 0.2% triton X100 and then blocked with 1%BSA, 4% goat serum prior to incubation with the primary 1antibody for 30 min at 37 °C. Bound antibody was detected using an Alexa fluor ® 488 Goat anti-Rabbit IgG (H+L).

Supplementary information

GRP94 also known as HSP90b1 is a glycoprotein that belongs to the heat shock protein 90 family. It has a molecular mass of approximately 94 kDa. GRP94 is expressed mainly in the endoplasmic reticulum and appears in high levels in cells undergoing stress. This protein acts as a chaperone assisting in the proper folding and assembly of other proteins playing an essential role in protein homeostasis. GRP94 ensures the quality control of proteins by preventing misfolding and aggregation.
Biological function summary

GRP94 influences the stability of many secretory and cell-surface proteins. It forms part of a multi-protein complex that stabilizes client proteins and assists their proper folding. GRP94 is essential for the maturation of proteins involved in the immune response including immunoglobulins and integrins. Overexpression of GRP94 has been noted in various cancers where it supports the folding of proteins required for tumor growth and survival.

Pathways

GRP94 is an important element of the protein folding quality control mechanism within the endoplasmic reticulum. It functions in coordination with other chaperones like BiP and calnexin within the unfolded protein response (UPR) pathway. The UPR pathway is essential during stress conditions where increased protein synthesis occurs. GRP94 also contributes to calcium homeostasis and directly interacts with proteins like integrins affecting cell adhesion and motility.

GRP94 has been implicated in the progression of cancer and neurodegenerative diseases. Overexpression of GRP94 is often linked to cancer where it stabilizes oncogenic proteins necessary for cancer cell survival. In neurodegenerative disorders GRP94 shows altered expression levels which may influence the pathogenesis of diseases like Alzheimer's. The interaction between GRP94 and other proteins such as tau protein in Alzheimer's highlights its potential role in disease mechanisms.

Target data

Molecular chaperone that functions in the processing and transport of secreted proteins (By similarity). When associated with CNPY3, required for proper folding of Toll-like receptors (By similarity). Functions in endoplasmic reticulum associated degradation (ERAD) (PubMed : 18264092). Has ATPase activity (By similarity). May participate in the unfolding of cytosolic leaderless cargos (lacking the secretion signal sequence) such as the interleukin 1/IL-1 to facilitate their translocation into the ERGIC (endoplasmic reticulum-Golgi intermediate compartment) and secretion; the translocation process is mediated by the cargo receptor TMED10 (PubMed : 32272059).
