Our Abpromise guarantee covers the use of ab80033 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • 生理活性

    1. The reactions are in 33 mM Hepes pH7.2, 30 mM NaCl, 5 mM MgCl2, 1 mM DTT, 1.5 mM ATP in a 100 µl reaction at 37ºC. It is an enzyme-linked ATP regeneration assay tracking loss of NADH absorbance at 340nm.

    2. The protein concentrations (where applicable) were 2 µM Hsp90 (SPR-102 Hsp90 beta), 2 µM Ahsa1 (His tagged human Ahsa1), 4 µM p23 (cleaved human p23), 4 µM HOP (His-tagged human HOP).

    3. Addition of a two-fold excess of p23 reduced Aha1-mediated Hsp90 stimulation by 30% (when using 2 µM Hsp90 and Aha1).

    4. Addition of a two -fold excess of HOP completely eliminated Aha1-mediated ATPase stimulation as well as intrinsic Hsp90 ATPase activity.

  • 機能Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function.
  • 配列類似性Belongs to the heat shock protein 90 family.
  • ドメインThe TPR repeat-binding motif mediates interaction with TPR repeat-containing proteins.
  • 翻訳後修飾Ubiquitinated in the presence of STUB1-UBE2D1 complex (in vitro).
    S-nitrosylated; negatively regulates the ATPase activity.
  • 細胞内局在Cytoplasm. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
