  • Function
    Inhibits the chaperone activity of HSP70/HSC70 by promoting substrate release. Has anti-apoptotic activity.
  • Involvement in disease
    Defects in BAG3 are the cause of myopathy myofibrillar BAG3-related (MFM-BAG3) [MIM:612954]. A neuromuscular disorder that results in early-onset, severe, progressive, diffuse muscle weakness associated with cardiomyopathy, severe respiratory insufficiency during adolescence, and a rigid spine in some patients. At ultrastructural level, muscle fibers display structural alterations consisting of replacement of the normal myofibrillar markings by small, dense granules, or larger hyaline masses, or amorphous material.
  • Sequence similarities
    Contains 1 BAG domain.
    Contains 2 WW domains.

  • All lanes : Anti-Bag3 antibody (ab47124) at 1/2000 dilution

    Lane 1 : Thymus lysates, total protein (20ug/lane)
    Lane 2 : Spleen lysates, total protein (20ug/lane)
    Lane 3 : Skeletal(quadriceps) lysates, total protein (20ug/lane)
    Lane 4 : Skeletal(diaphragm) lysates, total protein (20ug/lane)
    Lane 5 : Smooth (heart) muscle lysates, total protein (20ug/lane)

    Predicted band size : 62 kDa
    Observed band size : 86 kDa (why is the actual band size different from the predicted?)
    Tissue lysates, normalized for total protein (20 µg/lane), were from a 4 week old male mouse. BAG3 expression was detected at highest levels in skeletal (quadriceps and diaphragm) and smooth (heart) muscle specimens.
  • ICC/IF image of ab47124 stained HeLa cells. The cells were 4% formaldehyde 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 (ab47124, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 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.

  • Frozen mouse muscle tissue section stained for BAG3 expression using ab47124 at 1/2000. The tissue section was fixed in 3.8% paraformaldehyde prior to staining. BAG3 localizes with Z-disk proteins."
  • Immunohistochemistry of formalin fixed paraffin embedded human pancreas tissue sections using ab47124 at 1/2000. A, normal pancreas. B and C, pancreatic cancer. Hematoxylin-eosin counterstain.
  • Anti-Bag3 antibody (ab47124) + Hela lysate at 0.5 mg/ml

    Predicted band size : 62 kDa
  • Immunocytochemistry/Immunofluorescence of A431 cells stained with Anti-Bag3 antibody (ab47124) green. Nuclei and alpha-tubulin were counterstained with DAPI (blue) and DyLight 550 (red).
