Application Abreviews Notes
ICC/IF Use a concentration of 1 µg/ml.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 54 kDa (predicted molecular weight: 58 kDa).


  • Function
    Involved in the unfolded protein response (UPR) during ER stress. Co-chaperone of HSPA8/HSC70, it stimulates its ATPase activity. May inhibit both the autophosphorylation of EIF2AK2/PKR and the ability of EIF2AK2 to catalyze phosphorylation of the EIF2A. May inhibit EIF2AK3/PERK activity.
  • Tissue specificity
    Widely expressed with high level in the pancreas and testis. Also expressed in cell lines with different levels.
  • Sequence similarities
    Contains 1 J domain.
    Contains 9 TPR repeats.
  • Domain
    The J domain mediates interaction with HSPA8.
  • Cellular localization
    Endoplasmic reticulum.

  • ICC/IF image of ab72885 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab72885, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 Goat anti-Rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 4% PFA fixed (10 min) Hek293, HepG2, MCF-7 cells at 1µg/ml, and in 100% Methanol fixed (5 min) HeLa, HepG2, Hek293, MCF-7 cells at 1µg/ml.
