Target

  • FunctionActs as a repressor of transcriptional activation. Inhibits the transcriptional coactivator activity of CITED1 on Smad-mediated transcription. Chaperone. Isoform 2 may function as an endogenous inhibitory regulator of HSC70 by competing the co-chaperones.
  • Tissue specificityUbiquitous.
  • Sequence similaritiesBelongs to the heat shock protein 70 family.
  • DomainThe N-terminal 1-386 residues constitute the ATPase domain, while residues 387-646 form the peptide-binding domain.
  • Post-translational
    modifications
    Phosphorylated upon DNA damage, probably by ATM or ATR.
    ISGylated.
  • Cellular localizationCytoplasm. Melanosome. Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Translocates rapidly from the cytoplasm to the nuclei, and especially to the nucleoli, upon heat shock. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

Anti-Hsc70 antibody [1B5] images

  • ab19136 at 1/150 dilution staining human HeLa cells by ICC/IF. The cells were heat shocked (2 hours at 42.5°C) and paraformaldehyde fixed prior to incubation with the antibody for 1 hour at 37°C. An Alexa-Fluor ® 568 conjugated goat anti-rat antibody was used as the secondary. The cells were also stained with DAPI to visualize the nuclei.

  • ab19136 staining Hsc70 in Human breast tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 10% serum for 1 hour at 20°C; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody (1/150) for 12 hours at 4°C. A Biotin-conjugated Goat anti-rat polyclonal (1/200) was used as the secondary antibody.

  • Overlay histogram showing HeLa cells stained with ab19136 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab19136, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rat IgG (H+L) (ab98386) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rat IgG2a [aRTK2758] (ab18450, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
