Western blot - Anti-GRP94 antibody [EPR3988] - BSA and Azide free (AB238959)
This data was developed using the same antibody clone in a different buffer formulation (ab108606).
Lanes 1-3 : Merged signal (red and green). Green - ab108606 observed at 94 kDa. Red - loading control ab8245 observed at 36 kDa.
ab108606 Anti-GRP94 antibody [EPR3988] was shown to specifically react with GRP94 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266313 (knockout cell lysate ab257254) was used. Wild-type and GRP94 knockout samples were subjected to SDS-PAGE. ab108606 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

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.
