This antibody gave a positive signal in Recombinant Hsc70 protein as well as Human Breast and Human Kidney tissue lysates and the following whole cell lysates: MCF7; MDA MB 231; HEK293.
Storage instructionsShipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.
Storage bufferpH: 7.40 Preservative: 0.02% Sodium azide Constituent: PBS Note: Batches of this product that have a concentration < 1mg/ml may have BSA added as a stabilising agent. If you would like information about the formulation of a specific lot, please contact our scientific support team who will be happy to help.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Detects a band of approximately 75 kDa (predicted molecular weight: 71 kDa).
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.
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 modificationsPhosphorylated 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.
