Target

  • FunctionIn cooperation with other chaperones, Hsp70s stabilize preexistent proteins against aggregation and mediate the folding of newly translated polypeptides in the cytosol as well as within organelles. These chaperones participate in all these processes through their ability to recognize nonnative conformations of other proteins. They bind extended peptide segments with a net hydrophobic character exposed by polypeptides during translation and membrane translocation, or following stress-induced damage. In case of rotavirus A infection, serves as a post-attachment receptor for the virus to facilitate entry into the cell.
  • Tissue specificityHSPA1B is testis-specific.
  • Sequence similaritiesBelongs to the heat shock protein 70 family.
  • Cellular localizationCytoplasm. Localized in cytoplasmic mRNP granules containing untranslated mRNAs.

  • ICC/IF image of ab94368 stained HepG2 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 ab94368 at 5µg/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 formaldehyde (4%, 10 minutes) fixed HeLa, and MCF-7 cells at 5ug/ml, and also in Methanol (100%, 5minutes) fixed HeLa, Hek293, HepG2, and MCF-7 cells at 1ug/ml.
